mk11174: Thanks again for the newest (FIX2) build, and for your answer re: build environment.
Just tested out FIX2 and for me at least, 960x408 gives me only 85 frames instead of continuous, while 960x402 gave me a couple of hundred before skipping a frame. So raw performance seems to be just a hair worse with all this stuff enabled, as you probably suspected. Tested this with Hack on and off and with Global Draw on and off. FYI! Look forward to reading about your continued experiments. Cheers!
