Awesome, at least its working. So far I have mostly tested my games and rarely playing the whole game.
The one game I played from beginning to end is Hard Reset. It actually ran really well, no slowdowns and hardly any artifacts.
There were a few texture problems, but restarting the game would fix it.
Normally I play each test a few hours just to make sure everything is working. But I have read on WineHQ that some games crash later on or at a specific point in the game.
So no test is perfect, but running the game initially is a good start.
Keep trying and tweaking... make sure to post on WineHQ your problems and read up to see if other people have fixes.
Always try newer versions of Wine as they are released too.
I found that the older the game, the better it runs.
This last weekend I was trying to run the original Turok on my Chromebook (Intel HD 2000 GPU) and it runs but most of the graphics are missing. I tried everything and still got the same result. Probably a limitation of my GPU or Turok was never made for OpenGL.... its an old game though, you would think just a CPU could run it...
