Thank you for posting for me

i believe it only comes at the one resolution, to balance the scores- if we were using different resolutions that would skew the results.

I thought this was an app to test one's own system against VR specs (which I understand is at least 1440p?), not to measure against everyone else's?


Watched my friend VRtest his 12gb Titan X last night.
The scores just slammed right up to the max and stayed there. The graph was a flat line and he even had frames that were CPU bound (4770k, I think he's got).

I am jelly as a fish!!

It's a benchmark. PC enthusiasts will always compare benchmarks

As for the resolution, it looks like they're super-sampling to emulate it and put the same load on cards.

Well yeah, that's just a given...
But again, benchmarks are supposed to score the best your PC can do, not simply see if your PC can do what mine can, what hers over there can, and so on.

OK, that makes some sense... well, enough that I understand, anyway!

I was expecting a much worse result...

I just got 0.1 with an OC'd 750ti - I'm gonna blame a bug

You think it should be more like 0.01?

That was poor. My 580 managed an 11 (picture earlier in the thread)! Seems like a pointless tool if you ask me. How can a 580 be comparable to a 970 in anything but (I'm guessing here) directx 10... Most VR games will be in DX12 and the 580 won't be DX12 capable.

... How can a 580 be comparable to a 970 ...

If the VR rendering is compute heavy a 580 could do really well actually. Nvidia got the power draw down on later cards by hacking out most of the compute capabilities, with the 580 the last proper consumer GTX card with most of the compute power left in (that shifted to the Titan line thereafter).

The fact that Steam are providing a test that runs on DX11 cards gives a fairly clear indication that they are expecting the majority of VR-enabled titles to be DX11, or at least to have a DX11 fallback (iirc DX12 has feature-level fallbacks in the same way that DX11 did). Expect the second-hand price for GTX 580s to go through the roof on the back of this

Don't think I'm doing too badly on a P45 platform with a 9 year old CPU

The GTX580, it turns out, is an absolute beast just waiting to be unleashed!

Didn't know that. Interesting as i've started hitting a few performance issues with the 580 but on the whole it does ok. Glad I didn't make the jump on a 380 as I'd originally planned.

Well I've only just overclock my 3570k which may have helped

the test is a yardstick, and as such the yardstick needs to be the same for everybody
