This is a big release, adding several new major features:

• Nvidia support! LACT now works with Nvidia GPUs for all of the core functionality (monitoring, clocks configuration, power limits and fan control). It uses the NVML library, so unlike the Nvidia control panel it doesn't rely on X11 extensions and works under Wayland.
• Multiple profiles for configuration. Currently it is not possible to switch them automatically, but they are configurable through the UI or the unix socket.
• Clocks configuration now works on AMD IGPUs (at least RDNA2). Previously it was not parsed properly due to lack of VRAM settings.
• Zero RPM mode settings on RDNA3. Currently this needs a linux-next to be used, and the functionality is expected to land in kernel 6.13. But this resolves a long-standing issue with RDNA3 that made the fan always disabled below a certain temperature, even if using a custom curve.

There are many other improvements as well, such as better looking and more efficient plots rendering in the historical charts window (thanks to @In-line ) and a Fedora COPR repository providing LACT packages (currently in testing).

Memory managment

Resource and memory management were completely rewritten in order to use allocated video memory more efficiently:

• Reduced fragmentation may reduce peak memory usage in games such as God of War by up to 1 GiB in extreme cases.
• Memory defragmentation is now performed periodically to return some unused memory back to the system. The goal is not to reduce VRAM usage at all costs; instead this is done conservatively if the system is under memory pressure, or if a significant amount of allocated memory is unused. Keeping some unused memory is useful to quickly service subsequent allocations.

Note: Defragmentation is currently disabled on Intel's ANV driver, see #4434. The dxvk.enableMemoryDefrag config option can be set to enable or disable this feature via the the Configuration file.

Driver support

While technically not required, the new memory management works best on drivers that support both VK_EXT_memory_budget and VK_KHR_maintenance5. The Driver Support page was updated accordingly.

D3D8 / D3D9

Software cursor

Support for emulated cursors was implemented for the D3D9 cursor API, which allows games to set an arbitrary image as the mouse cursor. This fixes an issue in Dungeon Siege 2 (#3020) and makes the cursor appear correctly in Act of War and various older D3D8 games. (PR #4302)

Sampler pool

Unreal Engine 3 games using D3D9 have a quirk in that they pass a seemingly uninitialized value as the mipmap LOD bias. In order to avoid creating more Vulkan sampler objects than the driver supports, previous versions of DXVK would round the LOD bias to a multiple of 0.5, which could introduce visual inaccuracies. As a more correct soluition, DXVK will now destroy unused Vulkan samplers on the fly and use the correct LOD bias.

Note: The aforementioned workaround was never needed or used in the D3D11 implementation, it only affected D3D9.

Bug fixes and Improvements

• On Nvidia driver version 565.57.01 and newer, strict float emulation is enabled by default for improved correctness. Games for which this option was already enabled may see a small performance uplift on this driver.
• Made various changes to potentially improve performace on certain mobile GPUs. (includes PR #4358)
• Display modes are now ordered by refresh rate to be more consistent with wined3d and fix issues with some games picking the wrong display mode.
• Fixed a large number of wine test failures.
• Ascension to the Throne: Fixed old regression that would cause parts of the ground to render black. (#4338, PR #4341)
• Command & Conquer: Generals: Fixed performance issue caused by a missing D3D8 entry point. (PR #4342)
• King's Bounty: Warriors of the North: Fixed water rendering issue. (#4344, PR #4350)
• Tomb Raider: Legend: Fixed flickering geometry with strict float emulation. (#4319, PR #4442)
• Rayman 3: Fixed a regression that caused rendering issues. (#4422, PR #4423)

D3D11 / DXGI

Resource management changes

In order to reduce system memory pressure and improve stability in 32-bit games, creating, uploading and discarding resources is now throttled if the amount of temporary staging memory allocations exceed a certain threshold. This fixes crashes in Total War: Rome II and a number of other games. Additionally, large DYNAMIC textures commonly used for video playback will no longer use a staging buffer.

The d3d11.maxDynamicImageBufferSize and d3d11.maxImplicitDiscardSize options were removed accordingly; affected games such as Total War: Warhammer III and Ryse: Son of Rome should now perform well by default, without excessive memory usage.

Note: These changes negatively affect CPU-bound performance in a number of games, including Shadow Warrior 2.

Bug fixes and Improvements

• SEQUENTIAL swap effects are now implemented for DXGI swap chains, which allows games to read previously presented backbuffers. This fixes an issue wherein savegame thumbnails would appear black in certain visual novels. (https://github.com/ValveSoftware/Proton/issues/7017)
• Devirtualized some D3D11 method calls to improve compatibility with Special K.
• Fixed incorrect shader code generation for EvaluateAttributeSnapped.
• Lock contention is reduced in certain games that use Deferred Contexts for rendering. This may improve performance on older CPUs in Sekiro: Shadows Die Twice and some other games.
• Call of Duty: Modern Warfare 2 Campaign Remastered: Fixed a possible GPU hang. (#3884)
• Diablo 4: Work around an issue where the game does not start if an integrated GPU is exposed.
• The Sims 4: Work around a use-after-free bug in the game's D3D11 renderer for real this time. (#4360)
• Vindictus: Work around potential rendering issues caused by uninitialized constant buffer data. (#4405, #4406)
• Yakuza 0 and Yakuza Kiwami: Fixed a regression introduced in DXVK 2.4.1 that would cause these games to lock up on start. (PR #4297)

Miscellaneous changes

• An SDL3 backend was added for dxvk-native. (PR #4326, #4404)
• Fixed an issue introduced in DXVK 2.4.1 which would lead to error messages about failed buffer creation.
• Fixed a long-standing issue where overlapping occlusion queries would lead to incorrect Vulkan usage. (#2698)
• Fixed a rare issue wherein timestamp queries would not be tracked correctly and could read incorrect data.
• Fixed various other issues that led to Vulkan validation errors in games such as Dishonored 2, Tales of Arise and The Sims 4.
• Fixed various issues with MSVC builds. (PR #4444)
• Disabled a workaround for boken render target clears on Nvidia drivers prior to version 560.28.03 on unaffected drivers.
• If supported, VK_EXT_pageable_device_local_memory is now used to enable better driver-side memory management.

Today, we’re introducing Kagi Translate. It’s not revolutionary - it’s simply a better translation service.

Our combination of advanced language models and precise output selection delivers translations that surpass existing solutions, including Google Translate and DeepL.

Here’s a comparison table for main features:

*Quality ratings based on internal testing and user feedback
*Language count as of November 2024

For quick translations, documents, or daily browsing, the difference is clear in the first sentence.

Kagi in the wild

Here is this week's featured social media mention:

Tag our account or use #Kagi when mentioning us in your posts!

Welcome Auraxians! 

In today’s letter we have a very special announcement for you! Server merge! That’s right, we’ve been working on testing this major shift and are excited to share the details with you. 

Before we discuss that topic, we want to address the serious matter of cheating in the game. We understand that online cheating has affected your gaming experience, and as we tackle this issue and crack down on hackers, your reports and feedback are immensely valuable.  

Our development team is committed to improving the game and providing you with the best possible experience. We are actively addressing these issues and appreciate your patience during this time. 

Merging Servers 

We are excited to share that we will be merging the Cobalt and Miller servers tomorrow! We believe that this will not only improve gameplay for our EU players by creating larger battles but will also forge new opportunities for cooperation and competition between players and outfits that may have never faced off before. 

Over the last three releases, we have been testing a character porting feature to ensure that no data or progress is lost in the server merge process. Our tests have shown that the porting is complete and lossless.  

Tomorrow, October 29 at 6am PDT / 2pm CET, we will do a database backup and merge both Cobalt and Miller. Please check the status of your characters on that day and do not make purchases with DBC for at least the first 2-3 hours after the servers merge. If we see feedback that something drastically went wrong, we will revert the database state back to the morning of October 29. 

Also, please notify your friends and outfit members of the upcoming server merge so that the process goes as smoothly as possible for everyone.  

The following are some FAQs that should help with the merge process: 

• What will be the name of the merged server? 

  • We decided to keep "Miller" as the server name, home to both groups of players. 

• What about the other servers? Are you merging those? 

  • We want to review the results of merging our EU servers first. If all goes well we will evaluate the options to merge more servers later. 

• What happens if a player's name is already taken on one of the servers? 
  • Each player name is unique across all servers. There shouldn’t be any issues with your player name after the merge. 

• Does Daybreak All-Access membership transfer? 
  • Daybreak All-Access membership should be unaffected as it is linked to your daybreak account. 

• Will directive and mission progress transfer ok? 
  • Directive data should transfer just as fine, however we will monitor for any reports of missing data after the transfer. 

• What happens with Outfits on either server? Do all outfits stack up and co-exist in one server after the merge? What if an outfit of the same acronym exists already on either server? 
  • Outfits should remain unaffected by the merge but as this is a major shift of player data, we will review the results after the merge for any issues. 

• How long will the merge take? 
  • All servers will be offline for the merge process to complete which may take anywhere from 3 – 6 hrs. Please check our status on X for further updates. 

See you in-game!

Protecting young minds: Enhanced video safety for families

Your children deserve better than clickbait and shock value. We're making it happen with advanced video controls.

Family account owners can now shape a safer, cleaner video experience for family members:

Authentic thumbnails

• Replace misleading clickbait with actual video screenshots
• See what you're really getting before clicking
• End the bait-and-switch

Clean video titles

• Choose between title case or lowercase formatting
• Create a consistent, distraction-free experience
• Focus on content, not hype

Example (click to enlarge):

To access these options, navigate to: Settings > Parental Controls (section: Video Search Settings) or click here.

Why this matters

Recent research confirms a disturbing truth: children's video searches frequently expose them to inappropriate content, violence, and frightening images. We believe our children deserve better. Kagi's new parental controls help parents better manage the video content their children are exposed to, reducing the risk of exposure to inappropriate content and creating a safer online experience for them.

Help us protect more young minds - share your thoughts on making this protection available more broadly to all plan types. In case you wonder why we did not make this option enabled by default - video thumbnails and titles serve as a marketing tools for content creators, and changing them unilaterally would introduce us as a biased intermediary on a matter that is still in the air. This could have a negative impact for publishers and potentially conflict with our mission to "humanize the web". It is a delicate issue, and this is why we had propagated the control over this to the user level, as with all personalization features in Kagi.

Custom Assistant Bangs

Launch your Custom Assistant instantly from anywhere with a Bang shortcut. Simply set your preferred command and you're ready to go.

This seamless integration means your Assistant is always just a keystroke away, whether you're researching, writing, or exploring new ideas.

Improvements and bug fixes

@brjsp thanks again for submitting the concern here. We have made some adjustments to how the SDK code is organized and packaged to allow you to build and run the app with only GPL/OSI licenses included. The sdk-internal package references in the clients now come from a new sdk-internal repository, which follows the licensing model we have historically used for all of our clients (see LICENSE_FAQ.md for more info). The sdk-internal reference only uses GPL licenses at this time. If the reference were to include Bitwarden License code in the future, we will provide a way to produce multiple build variants of the client, similar to what we do with web vault client builds.

The original sdk repository will be renamed to sdk-secrets, and retains its existing Bitwarden SDK License structure for our Secrets Manager business products. The sdk-secrets repository and packages will no longer be referenced from the client apps, since that code is not used there.

This appears at least okay on the surface. The clients' dependency on sdk-internal didn't change but that's okay now because they have licensed sdk-internal as GPL.

The sdk-secrets will remain proprietary but that's a separate product (Secrets Manager) and will apparently not be used in the regular clients. Who knows for how long though because, if you read carefully, they didn't promise that it will not be used in the future.

The fact that they had ever intended to make parts of the client proprietary without telling anyone and attempted to subvert the GPL while doing so still remains utterly unacceptable. They didn't even attempt to apologise for that.

Bitwarden has now landed itself in the category of software that I would rather move away from and cannot wholeheartedly recommend anymore. That's pretty sad.

I recently switched from a MBP to a Framework 16 as my primary laptop and one thing I immediately noticed was that I was unable to stop kinetic scrolls in Firefox by laying my fingers onto the touchpad. It'd just slide by unimpeded. You could work around this by counter-scrolling a little rather than holding still which is how I've been coping with it but it's suboptimal to say the least.
(As are many things in the Linux touchpad experience. Linux desktop developers really ought to use a macbook for a little to get a sense for how to do this properly.)

This was caused by Firefox' use of GDK3 to implement its windowing and input needs which does not support hold gestures.

GDK4 does support them but, as I understand it, a port of Firefox to GDK4 would be a ton of work and there isn't really much desire for it as GDK4 doesn't offer many real advantages over GDK3 as Firefox doesn't use classical GTK widgets or anything and only really uses it for basic input/output primitives.

A backport to handle hold gestures in GDK3 too was attempted but, in classic GNOME fashion, it was rejected.

The implementation now somehow gets events from the touchpad directly via wayland somehow from what I could gather but if it works, it works.

You can try this out in the latest nightly builds.
