Sen - I think we're getting wires crossed a little - I didn't realise you were skeptical of the VirtuMVP as opposed to being skeptical of getting decent framerates solely on the Intel graphics alone. (Something which Kurayami posits is doable, and something which I will buy him a beer for if he can show it working).
VirtuMVP does do what it says on the tin - even if it can be something of an *** to set up.
Rough outline, it does three things:
a ) Like Optimus - it lets you swap between onboard and discrete GPUs as needed - but you don't have to be plugged into a particular display port. So you can plug into the onboard or onto the GPU but it'll work either way.
b ) Virtual VSync - lets you keep VSync on to stop display tearing but uncaps the frames being limited to 60
c ) Hyperformance - basically decides which things it doesn't need to do and drops them - so rather than 3 things trying to do the same thing, it'll strip it down so only one gets run - frees up GPU power for other stuff.
VirtuMVP from Lucid can work in two configurations:
1) Monitor plugged into onboard video
2) Monitor plugged into GPU
As far as game config goes - I'm running completely default settings with VSync turned ON. The reason for this is so the Virtual VSync ability of the VirtuMVP stuff can take effect (which can help to eliminate screen tearing).
With 1), this allows the GPU to be throttled back to allow for power savings - only calling on the GPU horsepower when required. This config was achieving >60 FPS prior the current patch. After the current patch everything was crawling along at 38FPS which was not so good.
So I went back to 2), which is the more gaming-oriented setup - which lets the VirtuMVP stuff work its magic. >60FPS the norm unless in intense battle (Radeon HD 6870 + i5 3470 graphics on the ASRock Z77E-ITX).
Of course, a few caveats:
You need Windows 7 or better (I'm presently using Windows 8 Pro)
Latest drivers help a lot (AMD being the provider of drivers in this case for my HD 6870)
Presently MWO uses DirectX 9, which I notice a lot of the benchmarks provided tend to try DirectX 11 games. DirectX 11 is still being worked on at present for MWO.
So in summary: VirtuMVP does *NOT* work with onboard alone. VirtuMVP simply provides a way to use onboard and discrete GPUs at the same time.
