Hi Diego Torrijos
I’m quite experienced with all the mentioned sw and KNOW how they work on the GPU side of processing data. do you know that Nvidia is BLOCKING performance under OpenCL in drivers by 50 % ? ( from 286.xx version of their drivers ) so even though it says it’s using the GPU at 100 %, in reality it’s lower than 50% ? so it can’t crash under the load you mention. It’s NOT possible. Look for good GPU monitoring sw, like MSI afterburner, and have a look at it at least there…
Download this http://www.ozone3d.net/benchmarks/fur/ and stress test you PC config… This one can get to GPU use like RC can do…
and send me the PC config + detailed PSU info please…
