@dmh43: what kind of performance problems?

@szymon_k: When I begin to fill up my canvas, the frame rate drops to a crawl

could you show some code?

I turned down the target frame rate to about 10 fps and now things work well (it doesn’t matter that it’s that low since it’s just a tetris game)

optimising graphics is hard

I doubt if thats something Quil-specific
