[Regression] MotoGP08 Graphical issue

[Triticum0]

Quick summary

The game has graphical issues and crashes past a certain build

Details

When testing this game I came across a shader cache issue which causes the game to have graphical issues and crash when decompiling shaders on the GPU.

The build that causes the graphical issue also crashes the game when first going ingame so not sure how I couldn't get an rsx file on the build that caused the issue. I should also mention that the crash also affects the latest build on both Vulkan and OpenGL.

Some build after v0.0.7-8619-7f99de36 do make it in-game without crashing but the graphical issue still persists. Was able to make it in-game twice with the latest build but didn't save the log there were two different graphical issues I got.

The first one was with default settings(This graphical issue does not appear on the original build with the regression)

The second one was with RDB+WDB+RCB+WCB which gives a different result(matches the effect of the build with the regression graphical issue).

Crash log:·F 0:01:17.076559 {RSX [0x427b530]} SIG: Thread terminated due to fatal error: Unknown register name: unk

Note: version 0.0.6-8608 regressed the game with a different issue causing the game to not display anything and was fixed on the regressed build so had to take a build before that build as a before log.

Other details

This is properly GPU specific

Have you tried using atomic FIFO?

[Virtua64]

This is the demo version. Got it to work with Atomic but it doesn't always work after reboot, even with the same exact settings. Trying to figure out why the inconsistency... video below is with Atomic enabled when it worked.

I tested it with atomic FIFO and it didn't fix the crashes

[kd-11]

Fixing the crash is easy by just ignoring the bad shader. Are the graphical issues still present with atomic FIFO is the question.

The crash should be fixed by #13361

[Triticum0]

@kd-11 The crashing has been fixed. You need to turn on the write depth buffer to fix the graphical issues. Turning on the Read Depth Buffer causes the blue screen and missing bikes. If you think the issue has been sufficiently fixed you can close the issue.

Thanks for the report. I'll close this and leave a comment in the buffer options ticket. Relates to #9133
