The game's performance is choppy.
This might simply be a result of low machine specs. Go into options and enable the FPS counter. If it's a value below 60 and the frame limiter is off, your graphics card might not be powerful enough to handle the game. Also check that other 3d apps in the background aren't eating up some of your precious graphics performance. If this is not enough, try checking the Low End PC option. DO NOT try switching to OpenGL to improve performance! At present, osu!'s OpenGL engine is neither as optimized nor as feature-rich as the Direct3D renderer. It is there for compatability reasons.
oh vram. OP wasn't mentioning anything about VGA as i readDexus wrote:
What are the vram requirements for osu! anyways? In fact what are the general recommended requirements for the game? I know people say you can play osu! on a toaster, but it doesn't really run smoothly.
I suggest you don't play on a cheap netbook, here's a recommendation if you can get it: http://amzn.com/B00K2U3CHG (It would be better if you could build a cheap desktop instead, but I don't know what your preference is.)
