SteamVR Performance Test

Getting 4.4 with dual Titan Blacks. Pretty poor TBH.

Anything below 90fps or where settings had to drop below medium to sustain fps gets rated poorly. SLI issue aside, a mild overclock would see you easily above that threshold with 1 Titan black.

Seems a bit of a stupid test if it does not work with SLI or XFire which does not use AFR in VR,since it dedicates one card to each display.

So realistically its not really that great a test,unless OFC SteamVR won't support dual cards which is dumb.

It appear Xfire is working. AMD claimed Nano's in Xfire get 11 in comparison to a score of 8 alone.

AMD brought this test to our attention, and the company actually sheds a bit more light on what this benchmark does than Valve's official release notes do. According to AMD, this test uses a technique called dynamic fidelity to adjust image quality to the level needed to maintain a high enough frame rate for a good VR experience.

Going by that description, the rather vague graph in Valve's report seems to tell us how much time cards can spend at various image quality levels. Unsurprisingly, then, the GeForce GTX 980 Ti's flat line at "Very High" means it didn't have to adjust image quality at all, while the GeForce GTX 970's more variable graph might indicate that more on-the-fly graphics settings changes were happening behind the scenes to keep frame times down.

I'll give it a bash. Was going to try with SLI off and a mild overclock tonight, actually. See what that does...

Useful link, thanks.

My rig failed woefully, down to my GPU apparently. No great surprise there, though it didn't appear to be running X fire and it would be interesting to see if it was capable as 2 X 7950s.
