Sheeesh, that CPU use during animations is ROUGH... Was really enjoying it up until it started to literally kill my computer running a choppy animation, not even graphically intense next gen games stress out my rig like that. I know it's 4k, but it's straight murder on the CPU the way it is right now, and I can't possibly see any reason for it to run that badly for 4k pictures that look like that.
Guess I'll switch to the 1080/compressed, instead.
Edit; Nevermind. Even the most compressed version is using an insane amount of CPU. Never seen this before with a renpy game.
