I've been wanting to run r2 for years and have only just started practicing some things about a week ago but I'm worried that since I'm running the game on Linux through wine that my runs wouldn't be considered as legitimate. Only differences that I've noticed are to do with textures appearing black for a second or two.

edit:
Managed to find a solution to the texture issues from Steo on the raymanpc forums by running winetricks to ensure the prefix had d3dcompiler_47.
Now the only problem is occasional audio crackle.

Hey, running the game on Linux is perfectly fine, as long you don't notice an obvious game boost - which we have often seen in Windows as well.
If you are using the Ray2Fix graphics fix, you should be fine.

Yeah the game runs just fine at 60 fps with no changes to physics.
