Rayman runs great, nice visuals in big resolution.
Republic Heroes are not running good, very sluggish.

Rayman Origins

Running great 25-50 FPS in 1280x720 resolution.
For max 60 fps use 800x600 and smoothest gameplay.
If you notice slowdowns, I didn't, then use lower resolution or try to put game in windowed mode.

Star Wars The Clone Wars Republic Heroes

Runs in 5-18 FPS, mostly slow, but sometimes it is faster.
For me playable but very slow, and also game has very poor gameplay and story.

It doesn't have any configuration file.
