Valve's SteamVR Performance Test assesses PC VR readiness

[HEXUS]

A 2-minute sequence from Valve's Aperture Robot Repair VR demo is behind the test.

My PC is ready... to be upgraded

[Platinum]

Ill be ok

[tonyd223]

But buying another GTX 970 for SLI means I have to buy a new power supply as well, so £270 become £370...

[Fluffmeister]

I'll be OK too!

I have a 970 and a 290X, both running 'first gen i7s' (overclocked Xeon L5639s). I don't have any intention of buying a VR headset any time soon but hey, always interesting to see where you stand.

970 - 1st one stock, 2nd one 110% power limit, 3rd one +100MHz core clock and +500MHz mem clock to give ~1428MHz / 8GHz during testing:



(BCLK is 200MHz so CPU will have run between 3.6GHz and 4.0GHz depending upon how many cores were in use)

There's no decent scale but I overlaid the lines for the hell of it:




290X - 1st one stock (1010MHz core, 5GHz memory), 2nd one 1100MHz core, 6GHz memory, 3rd one 1150MHz / 6.2GHz:



(again BCLK of 200MHz but the CPU ranges from 3.2GHz up to 3.8GHz in this PC despite it being the same CPU - BIOS / motherboard issue)

Odd that the 290X scores higher but rendered less frames during the test.

Overlay of the 290X results:

I'm good, just need some VR gear now.

Gigabyte GTX960 and a Xeon E3 1230 V2/Core i7 3770.

Stock Results.



Having said that the score was 2.9 when I benched the card from cold.

Results with GTX960 overclocked to around 1.45GHZ and aroubd 1.973GHZ for the VRAM



There seems to be nearly a 50% increase in score overclocking the core around 125MHZ more and the VRAM around 450MHZ more!!

Somebody with my same card overclocked to a similar amount with a 4.5GHZ Core i5 6400 score 4.5 - the benchmark seems very poorly threaded IMHO if the score is true.

Also it seems on Reddit a GTX570>>>>HD7870 which is LOL.

But buying another GTX 970 for SLI means I have to buy a new power supply as well, so £270 become £370...

SLI or XFire does not work with SteamVR it appears and leads to worse performance!!

[Marenghi]

good news for the cpu at least, 50% on all cores whilst running the test

[failquail]

Not that i have any real interest in VR, but the little demo animation was fun



(CPU currently OC'd to 4.2GHZ)

Edit: regarding the very low numbers some are getting, is it simple GPU RAM overflow causing excessive bouncing of data across the PCIe bus?
My GPU was using ~3.4GB video RAM during this test, i'd imagine 2GB cards would choke on that...

[Ttaskmaster]

I probably won't even try the test... Not sure I could stand for Steam insulting my little baby!!

[malfunction]

I can get the 970 up to 8.4 (+33% vs stock) with a bit more overclocking (~1528MHz core, 8.3GHz mem during the test):



Taking the 290X further doesn't do much - 1150Mhz is pretty much the max for the core and taking the memory up to 6.4GHz helped a bit looking at the graph but not enough to increase the overall score from 8.7 (still +22% vs stock).

[Bluecube]

Doesn't work on OSX. I'm dooooomed! I'll try it on my SteamBox later.

[kalniel]

My 7870 made it to the upper half of the Not ready zone at least, so yay, it's performing better than most 7000 series cards. But still not fast enough.

Mines ready with a R9 290 Vapor-x
