Hi all, I've been trying to run rFactor 1255 and Racer (with CG shaders) games with Wine 3.9, with a very similar fatal error, related to shaders.
Racer is a free game you can get in the official developer's web [url]Racer.nl[/url]
RACER

What GPU are you using?
I'm using a Radon R9 285 with mesa, and I get the same errors.
I'd guess that it's a graphics driver issue, not a wine problem. But I'm not 100% sure.

I got the program from http://www.racer.nl/dl_beta_win.htm, and it states that they "work almost exclusively with nVidia cards (and drivers), so those are highly recommended for the best compatibility with Racer".

Hmm I have Intel 4th Generation Integrated Graphics, the thing is, I've never had this issue on any game when I had Windows...
Also, what about rFactor problem? is it the same issue then?

I don't have the game, so I can't test. I guess best would be if we got someone with nvidia and proprietary drivers on linux to test it. If it works there, it's a driver issue, if it does not, it could be wine.
