Every game running OpenGL would hard lock after a few minutes.
What I did to fix it:
1.Un/Reinstalled latest Deto drivers (v29.20)
2.Set ‘optimal’ refresh rate in adapters tab of control panel
3.Selected ‘general timing formula’ in information/additional properties/other options tab.(never let winblowz do anything for itself)
OpenGL crash problems go bye-bye.
As my Grandfather used to say “Timing is everything”
In my case, this was certainly true when trying to play in OpenGL mode.
I hope this helps other folks who are having the same issues.
