Kombustor Stability Testing with OpenGL v. D3D -
| posts: 70 | Location: Minneapolis, MN
I've been using Kombustor 1.1.2 over the last few days to get a stable OC on my new HIS 5770. It's been going well, but then I discovered a drastic difference between D3D and OpenGL results. I was hoping people here could weight in with their thoughts on the results.
In D3D11 @ 950/1375 I can run Kombustor for 45+ min w/ 8xaa. It may go longer, but I just stopped it at 45 min.
However, when I run it in OpenGL 3 @ 950/1375 w/ no aa, it can only run 2 min. I continued to drop down the memory overclock, stopping @1300. @ 950/1300 it can't make it more than a few minutes.
My Question: Is there something abnormal about this, or are the OpenGL benchmarks more strenuous?
