Direct3D 9 does not display images of 3D games on Nvidia GPU

[teorex3]

I have a graphical issues after implementing vertex range culling #11393

Tested on:
ppsspp-v1.6.3-472 - working OK
ppsspp-v1.6.3-478 - NOT working
ppsspp-v1.7.4 - NOT working

GPU: Nvidia 7600 GT

maybe this is help too?..

Strange. I guess we'll have to turn it off on older NVIDIAs as well indeed..

[hrydgard]

@teorex3 But the menus work, right? If you go into Settings/Tools/System Information and look at the Vendor line, what does it say exactly? Would need to look there to detect old NVIDIAs in D3D9 I think...

[teorex3]

This report from OpenGL Extensions Viewer, also contains information about D3D:

Thanks, I'm gonna try to make something to detect old Geforces, working around this problem.

Anyway, any particular reason you're using D3D9? D3D11 should work better for you.

[teorex3]

One reason is no support D3D11 on NVIDIA 6xx, 7xx, if i run with D3D11 plugin, I get APPCRASH PPSSPPWindows.exe error.

You mean 6xxx, 7xxx. But crashing is unexpected... Darn.

It probably means we're doing something that isn't supported on feature level 9? Could be npot textures or separate alpha blend at 9_1, even...?

Unfortunately, I don't have anything older than 8xxx.

Try turning off settings: hardware transform, hardware tessellation, anisotropic, maybe even skip buffer effects. If any of these help, it'll help us narrow down the cause.

It seems like we use ps_4_0_level_9_1 on D3D11 with < 9.3 support, but then try to use some higher level features anyway (like bitwise shader ops.) This appears to affect UWP.

@unknownbrackets We don't expose D3D11-feature-level-9 except on UWP, this is an issue about real D3D9 problems, so not related. But yes, we probably have a few cases like that...

[unknownbrackets]

I was referring to "if i run with D3D11 plugin, I get APPCRASH PPSSPPWindows.exe error."

I wonder though if setting w to 0 would more likely work. That it breaks rendering even that shouldn't be culled implies to me that it just has trouble because a nan is involved in the conditional.

Has this improved?

yes it helped

Thanks for testing!
