Comment # 150 on bug 80419 from ArneJ

I also suffered a lot from this issue on my R9 270X.
I was never able to go past the first tutorial mission because my PC hung
during that mission.

Now I tried it again with mesa 13.0.3 and I was finally able to finish the
first mission and also played 3 more missions after that without any issues.
It looks like this issue is finally resolved.

Thanks a lot Marek!
