[d3d9] Sonic And Sega All Stars Racing / Lara Croft and The Guardian Of Light: heavy stuttering
This game suffers from heavy stuttering when racing for the first time in all tracks (also they prevail even in subsequent runs for some of them). I understand shader compiling on Linux is expected, and my experience with D3D9 games using DXVK is smooth in most cases (some titles have soft stuttering, but they fade in subsequent runs). I have only opened this issue because the stuttering seems odd for this title (it actually may be doing something wrong, but I don't understand the apitrace to confirm that unfortunately).

This problem is not specific to DXVK. I had the same problem years ago on Windows and if you search on Google about it you'll see many people being affected by the same problem. That's just how the game works, it compiles shaders at run-time.
Well, for such cases would it be possible to enable asynchronous shader compiling to avoid these hard locks ? This game is old, has only local multiplayer and no anti-cheat software.
Asynchronous shader compiling is a hack that isn't supported by DXVK because it's known to break games.
with good reason. Just wondering how many other games use this and / or if its worth even adding it as a separate flag
The game compiles shaders from hlsl at runtime, is what I believe is the problem? (In this instance)

If it does, then that happens on the loading screen. All graphics pipelines used in the apitrace are created on the loading screen on subsequent runs (state cache).
I can't reproduce the stuttering using the apitrace and I don't own the game itself.
Guys, it seems the same issue affects "Lara Croft and The Guardian Of Light". The Steam client took 15-20 minutes to compile the pre-shader caching, and even so the game stutters for every step moved by the character in the primary levels. Basically every new area it stutters heavily. I'm going to let the API trace of this game attached as well.
Updated specs:
- GPU: GTX 970 4Gb
- Driver: 510.60.02
- RAM: 16 Gb
- CPU: Core i5 4690s (3.2 -> 3.9)
- Kernel: 5.15 (futex2 patched)
@ranplayer Please retest both games with dxvk 2.0 and the 520 nvidia driver if you can. Note that atleast Sonic And Sega All Stars Racing also does it's own shader compilation and it's not possible to rid the stutter fully.
@Blisto91 I'll retest them this week and let you know. I'm out of Nvidia hardware atm, so I'll be using a RX 6700 XT
Oh then never mind hehe. The extension that should help with stuttering isn't available on AMD yet.
I've tested both anyway. Sonic seems to stutter less (compared to my old Nvidia GTX 970), but Lara Croft still stutters too much.
I've done a bit of testing back and forth in the beginning of the Lara Croft demo between the new extension and the old shader compiler system on my R9 380X and the radv driver. At least in my short testing it seems to have improved it decently. I have an issue in the game where i get huge framespikes whenever i move my mouse around, but with a controller i didn't experience that. Not sure what is going on there.
Sonic And Sega All Stars Racing is harder to do anything about since it also compiles it's own shaders. Which is probably what hurts the most.
@Blisto91 what version of Mesa did you use ? Did you enable any specific flag ? I can give it a go here.
mesa-git (mesa 23 can also be used when it arrives) and RADV_PERFTEST=gpl
And then use Proton Experimental or bleeding edge.
Note that for RADV it is still a work in progress so cache isn't working at the moment.
Indeed... just tested here both titles using Proton 8.0 and Mesa 23.1.0 and all the stuttering has gone. Sorry for the really late reply (I've been waiting for the final 23.1.0 release for testing both games). Thank you, folks.
