#158 OpenGL stability with shaders

[2mg]

I'm having random crashes with OpenGL and xBR shaders. Usually I get "Program has stopped working", out of bound memory error, or the middle of the screen freezes. I am unsure if it's OpenGL itself or xBR, since I had a crash on OpenGL too. I'm not having problems with OGL+xBR on other emulators.

*I am trying to find xBR-hybrid since or a newer xBR since it works better with NVidia GPUs while waiting for a fix.

shaders?

our code doesn't support 'shaders', the filters are purely software, so opengl/d3d should not matter at all.

Yes, filters (sigh, nomenclature...).

Since they are purely software, I guess OpenGL isn't stable in the latest release? A friend of mine never had a crash on D3D + HQ filter.

OT: don't wanna open a new ticket - will VBA-M switch to .cg format? I see it's using outdated Kega Fusion .rpi.

Bump for a big edit on my previous post.

Been playing a couple of days with D3D + xBRZ and DirectSound 8, flawless!

I'll try with xBRZ MT to see if it crashes, since using filters grays out the Multihtread option.

I reckon OGL is unstable, either alone or just with filters.

Confirmed that xBRZ MT crashes even on D3D.

To recap:

• xBRZ MT .rpi crashes both D3D and OGL
• OGL seems unstable by itself, especially with filters
• Multithreading option is disable when using filters for some reason

There is clearly something wrong with your computer or its drivers.
