Hi guys,
Does anyone else have a 768mb gtx 460 they can try running heaven benchmark with as mine seems to be experiencing random slowdowns in heaven in a couple of stages.

Most stages are fine (about 40-70 fps in dx10) but some stages drop suddenly to about 2-4 fps. :(

In what sense?

"slow downs" are generally a decrease in fps, which is what benchmark is designed to push

Sorry, just added a bit more information in the op. :thumb:

Just to add, it happens at stock clocks and OC'd to 840/1680/2130.

not sure about heaven benchmark but in Vantage one test drops you to 1 fps.. this is normal as it hammers the system, maybe its that?

After more testing it just seems to be the refraction option in heaven that it really dislikes. After turning that off I am now getting better dx11 speeds than my brothers 5850. :thumb:
