The rendering here is extremely unoptimized. On a GTX 1060, frame times are consistently well over 50ms, which makes the game unplayable. Performance is better on an RTX 2080, getting around 18ms gpu frame times on average when running native (far more playable!), but GPU usage is still pegged at a constant 100%. Both GPUs were rendering to 1080p displays. We had to bust out Renderdoc to double-check that the game isn't a crypto miner, as the performance issues were pretty alarming.

The performance issues seem to stem from the sheer amount of full-screen gaussian blur (this is a fairly expensive operation!) being done every frame. Quite a few render passes seem to have their results go completely unused within the final presented frame.

Optimization issues aside, this is a pretty solid rhythm game! The vocals and backgrounds are fairly repetitive, but the underlying songs have decent variety. The presentation makes sightreading fairly intuitive, though the hard charts aren't particularly challenging.
