Quoting: elmapulwhat about games and applications that only work on older versions of wine?

That shouldn't normally happen. If it does, it's a bug that should be reported as a regression.

Fun to see especially for me, as today is another day of booting up the GamingOnLinux work machine to be greeted by NVIDIA proprietary driver problems.

Did your order of 7900 XTX not work out in the end?

Quoting: jordicomaIt already needs a signed firmware in order to boot the graphic card, the same as amd.
It's not 100% opensource graphic stack for the firmware, but it's more flexible than having all the stack propietary.

I think concern is that Nvidia gives no guarantees about stability of interfaces to use that firmware. They can easily bork things for the open stack by changing something, like they for years were not allowing Nouveau to reclock in the first place. So the fact that now it's possible still relies on Nvidia being in a better mood, and they are nasty in general.

So of course it's great that reverse engineering efforts are now able to achieve more and there is some work on the kernel interface, but it's still on shaky ground unlike with AMD who are working with upstream kernel directly.

If Nvidia will work with upstream for a change, that would be much better.

Quoting: CreakIs there a benchmark somewhere to know the performance difference between vkd3d and VKD3D-Proton? And also, is Valve planning on using Wine's implementation at some point?

From what I gather, you shouldn't worry or care about Wine's vkd3d for gaming scenarios or on Linux in general. vkd3d-proton deliberately focuses on newest available Vulkan features to get best possible performance. Wine's stock vkd3d tries on the the other hand to target crippled cases like Vulkan over Metal on macOS, so performance is traded for wider compatibility by avoiding new and advanced features that only work on real Vulkan in practice.

So for gaming, vkd3d isn't a good option. For some desktop applications - only if you care about macOS at least.

Quoting: Guestyeah and also faster. linux boots up in 1.5 seconds, yet before it uefi takes 8 seconds to initialize. that's awful

I've heard DDR 5 on Zen 4 takes a long time to initialize in general. Didn't get one to test yet.

It works with CP2077 and The Witcher 3. Performance isn't really on a playable level.

This is pretty cool. I wish actual UEFI for common motherboards was also open source.

Quoting: Loftybut isn't that what CAS basically is if you turn on TAA or FXAA in game. Your basically getting a similar thing, which is edge contrast, adaptive sharpening. correct me if im wrong.

May be, but FSR can be applied as an external filter, even if the game doesn't use the above. So may be someone can implement temporal antialiasing as a Vulkan layer. Unless some already exists for that?

I'd say this real time ray tracing is indeed more of a marketing thing now, because it just doesn't work well without upscaling. Once we'll get to the point of it working with native resolution with good framerate, then it will be really useful.

It's the reason I'm not using it yet. Experimenting with it is fun, but practically it's not there yet.

On a side note, temporal antialiasing doesn't need to be tied to upscaling. Just becasue DLSS / FSR do it, doesn't mean one depends on the other. I.e. games can as well implement temporal antialiasing on native resolution if they wanted.

For FSR to be more useful, it should offer it on 100% resolution as well (no upscaling at all).

Managed to make CP2077 work with ray tracing without hangs thanks to help from vkd3d-proton developers. It was just an unusual prefix mess up with Wine-staging at some point dropping an invalid nvapi64.dll in there that messes up CP2077 on AMD.

Performance of ray tracing is still not usable without upscaling even on 7900 XTX, but at least it's a fun experiment.
