Thanks , i've read it. If it is being tracked, i will close this. One question tho ; same situation also exist on DXVK i assume? Since i saw various people on Reddit etc complaining about stutters and low perf with dxvk titles too.
Yes, it can also affect DXVK. So far it seems to only affect 32-bit titles, but I'm not sure if that's actually true. We should have a fix for it very soon.
Thanks for the answer. Might be affecting dxvk also because strangely despite i even used shader_build there are frametime spikes ( stutters ) happens on Witcher 3.
It wasn't like that before.
Sleeping Dogs Definitive Edition - 64 bit


It affects dxvk and 64 bit titles as well it seems.
This should be fixed in 4.11-9. Please retest.
I've tested both games on 4.11-9 and issue is fixed. Thanks. Closing.

As described in the title. With Proton 4.11-8 D9VK you will see periodic frame time spikes while those spikes doesn't happen if you replace it with release from projects Github page.
