Literally spent 2 hours trying to record this with GeForce ShadowPlay beta It actually is at least 20 times more efficient than Bandicam (600fps when recording at 1080p@60fps on ShadowPlay vs 25fps when recording at 1080p@30fps on Bandicam on this PC). But it really doesn't like osu! at all. The recording just breaks during screen transitions (it stops recording by itself before the results screen and doesn't save a file). I really like ShadowPlay's performance, I just wished it worked properly
So I gave up and recorded it in Bandicam at 768p. Still disappointed since YouTube only takes 30fps anyways
