Will 2 Radeon R9-270 2GB in Xfire (OS W10home) run Oculus Rift?
All other requirements of Oculus Rift my computer is OK! I used Oculus Rift compatibility engine to check my computer, said all ok but Radeon R9-270!
The answer is no. Two R9-270s do not even equate to the power of a single R9-290.
No, thats wrong. They perform pretty much on the same level. Only in some single games/benchmarks 270 CFX or 290 is significantly better. But they both have stronger games and weaker games.
There is a really good review on exactly this question here:
Radeon R9 290X vs. Radeon R9 270 CrossFire - Graphics cards > Versus - Reviews - ocaholic
Also a little example video for many games:
R9-290 vs CF 270x (tests only) - YouTube
The Oculus tool says that my CPU is not up to spec. It's an FX-8350 stable overclocked to 4.7Ghz. I realise it is their tool but I seriously doubt that they are making a product that only works with Intel CPU's.
3rd party benchmarking software such as 3D mark give my system a score that beats their baseline for Oculus by a wide margin, including my 2 * R9 270 in Crossfire. Whether or not 2 * R9 270 in crossfire will work with Oculus is more about the game than it is the hardware, which comes down to the game developers code optimization and AMD 's ability to have decent drivers.
At this point I am more concerned about AMD updating crossfire profiles in a timely manner than I am about spec requirements of the Oculus. Because lets face it, they are well behind the curve on profiles, despite it being a main marketing point for their products.
the graphics memory does not add on together.there is no 2+2=4.the memory stays at 2
