... very nice GC ...!! ( Render:
GeForce GTX 780/PCIe/SSE2)
Well it looks like you're not using OpenGL but DirectX instead, so you're not getting the best graphical quality, which is a real pity considering your wonderful GC ...
You are not using 64 channels either (num channels 32 instead of =64) which is somewhat surprising since the "Audio Device" mod that allows the use of 64 channels comes with UV3 ... but you are using the too stressing 44100 sample rate instead of 22050 ...
Please try this (bold characters) in your conf.ini (backup yours first ... as usual...):
