100% CPU use is normal for SEV, I don't know about the RAM. If you're trying to do anything else while it's running, it's a good idea to set the priority of the se5.exe process to 'Idle' in task manager. This basically tells windows to let all other programs use whatever cpu they need first (0.1%), then allow SEV to use whats left (99.9%) so SEV runs the same, and other programs run as normal, rather than slow thanks to SEV hogging everything.

I've had the problem with the white flashing too, and found setting it to use 16 bit color instead of 32 fixes it. It seems to occur after minimizing the game - when it's restored it flashes. If you do stuff in the background while running the game, and have to run it in 16bit color like me, it helps to make windows run in 16bit color too - takes less time to alt-tab, and you don't have your monitor changing resolution and carrying on every time.
