    > Replying to https://github.com/ValveSoftware/Proton/issues/9789#issuecomment-6357274770 That's why I added that option as an extra boot option. And regarding that amdgpu patch. That's been going on for a long while, it...

    As others have reported, I saw a significant reduction in stutter by setting `vm_update_mode = 3`. However, this also introduces _new_ unplayably bad stutter for me in some other titles, like Cyberpunk. More interestingl...

    Good indicator indeed. In my experience, while the 1% lows are stable, they are still generally still lower while driving and looking around (~45) compared to standing still (~75) on a 90 FPS cap for my system. @Shijikor...

    Adding a data point here, and wow. Even on RDNA2 (RX 6600), adding `amdgpu.vm_update_mode=3` to /etc/default/limine under `KERNEL_CMDLINE` and running `limine-update` makes a massive difference. Before: After: System spe...

    just came in here to comment as I am also trying this out. I have resizable bar on, so ymmv, if you are a rocm/compute user `amdgpu.vm_update_mode=1` can have hindered results. `amdgpu.vm_update_mode=3` seems to be the g...

    > 31\. Yes, I did try the mode 1, and yes you should try it out on your system as well. [@linoshkmalayil](https://github.com/linoshkmalayil) > I saw no noticeable difference from mode 3 both in terms of average FPS or 1%...
