Oops, I accidentally forgot to disable debug output in the release build.Not sure if the console window spamming 2000 messages a second is impacting performance, but here's a comparison of Mario Kart 8 at the same moment on both, playing a replay after one restart to compile the shaders beforehand:
r0 (18 fps):View attachment 39781
r1 (21.13 fps):View attachment 39780
Intel i7-4700HQ CPU @ 3.2 Ghz turbo, GTX 870M
I have reuploaded r0 and r1, same download link. Could you try again? It should run faster without the console spamming. Thanks!
