I'm working on DolphinVR and found that updating to 0.4.3 caused a serious visual quality drop on 2D menu's and scenes in OpenGL mode. The effect looks like large amounts of chromatic aberration, combined with edges constantly crawling (almost like aliasing) even when the headset is stationary on a desk. After a lot of debugging, I've found the source of the bug:
In CAPI_GL_DistortionShaders.h, line 319-321, the following was changed:
This is the source of the issue. Reverting these lines back to TEXTURELOD and building my own custom 0.4.3 SDK fixes the issue. Can this be fixed in the next SDK version? Is there any advantage to using TEXTURE, rather than TEXTURELOD? It's possible that the AMD drivers don't play well with TEXTURE as well. I don't have a Nvidia card on hard to see if the same thing happens on Nvidia systems.
My specs: Windows 7 x64 AMD 7970HD GHz Edition (14.7 RC3 Drivers) Intel i5 3570 @ 4.4GHz 8GB RAM
Any input would be appreciated! I may see if I can get it running on my laptop with a Nvidia GPU, to see if the same thing happens (even if it only displays at 5fps).
