Unsynchronized part of the image in the game TWD saints & sinners

[MakaiHanta]

VR kit: oculus quest 2 Game version: steam PC: GTX 1060 6GB, i5 11-gen 11400 2.6 GHz, 32 RAM, HDD, windows 11

Something like vertical desynchronization occurs, but the cliff line is not horizontal, but curved. Tried different combinations of settings, but nothing helps. The same openvr_fsr works fine. If there are variants how to solve the problem, please help me (I'm not a programmer). Otherwise this is a bug report.

The image roughly shows how the game is rendered when you turn your head to the right

Happens on Oculus as well, but how'd you get it to work on Steam in the first place?

[MakaiHanta]

To be honest, I myself don't understand how VR games work. This game was purchased in Steam, the runtime environment of VR games is Steam VR. But some games like this still run through the Oculus environment. Of course, I couldn't launch it via steam VR

Some games like Sprint Vector will outright crash if you have Revive installed(allows SMAA on Oculus games) and try to launch them with SteamVR open.

This was already reported in #8 and is a known open issue. It only affects the Oculus runtime, SteamVR is fine. I don't know what's causing it and don't know how to properly debug it, because unfortunately using a frame debugger like RenderDoc crashes the game.

but, by the way, in games like deemo and super hot, which also run in the oculus environment, this mod works perfectly. I think in this case the problem is in the game itself, not in the environment

Check if TWD:S&S is using the deferred renderer instead of forward rendering like most UE4 VR titles do. TWD:S&S does a lot of very weird things that breaks compatibility with other things.

I know that Asgard’s Wrath for sure uses the deferred renderer.

The rendering method is irrelevant. At the end of things, the game submits one final image per eye to the runtime, and that's what vrperfkit intercepts and post-processes. The desync suggests that it may be mixing up the order of frames, but without seeing a frame capture, it is really difficult to pin down what's going on.

a little naive, but maybe try to write to the developers? You never know, maybe they will agree to help you develop a mod (unless, of course, you have already)

Skydance Interactive has moved their staff away from Saints & Sinners development and are actively working on Chapter 2.

Have you tried using other debugging tools to get capture from the game to figure out what sort of weird jank is going on with that game’s specific build of UE4?
