All i can do is to give several versions to find which build have issue "implemented" first, then try to turn code changes and test again. Are you able to make such testing? Btw, bf4 or other games are not the meter of stability, my mod is much more agressive to videocard.
You totally wrong. Bad drivers react on any change in shaders, even harmless one line.Does not explain why .236 works fine
Folks, i'm having awful issues with compilation of ssao shader in supersampling mode. It's too much complex and use all 32 temporary registers, so if i trying to modify something, to improve quality or to optimize even more, it not work any more. What if i reduce quality of it by 1/4 to free up required registers and use extra code to clear triangulation artifacts f.e.? Visually image will be more like without multisampling, performance is also 1/4 times less. Or i can make extra computations to "compress" several values in same registers, but this will affect performance, about 5-10% cost for modern videocards.
