It's set up by default in mine.

If you go into the applications bit in the settings Heaven should be listed. If it's not add it and tick the H box for HyperFormance.

I can't see Heaven listed? Is it called "Heaven" in the list or does it go by some other name?

It's listed under "Unigine Heaven Benchmark" in mine.

okay I didn't have it, should it work in D or I mode?

D mode, that's for Discreate Graphics (so your graphics card)

I Mode is it your using your cpu's internal GPU

Make sure you tick H as well.

Done that and ran a bench.

Before: 57.6FPS (1451)
After 58.5FPS (1473)

It only gives a tiny increase but not as much as 30 FPS more :eek:

Strange, Have you got the newest version of Virtu MVP?

My dabbling with MVP led me to believe that it is pointless. Some games show slight fps benefits, others show losses and some won't even start with MVP enabled. It also seems to work better with NVidia cards than AMD.

Forget about it until the technology improves.

yes, does it rely on some other driver or application to be enabled to work?

Arron17 · 11 May 2012 at 21:18

I have the exact same version... I wonder why it's giving me such a huge FPS boost...

What CPU do you have?

Same Processor too... I have no idea then lol.

Turn off virtual vsync?

I find it a bit suspicious getting a 42% increase using MVP. When review benches show a marginal 3% increase at the most. If the games you play boost by that many frames then I'm impressed.

Oh yeh that's what I did, I thought because the bench isn't using vsync then I won't need it and turned it off.

just did that and ran heaven and got a grey screen.

Arron17 · 11 May 2012 at 21:44

Yeh, it seems to do strange things, if i put virtual vsync back on I get normal FPS again but I get glitching with the textures. I'm guessing without virtual sync I might be getting massive fps gains because the MVP thing isn't working properly and it's not rendering everything so I'll get higher fps.

I think I might just disable it, it seems to cause more problems than good...

Twirlywoos · 11 May 2012 at 21:50

Just rebooted, turned of Virtu VSync; Ran Heaven and my framerates got worse 52.1 FPS 1313 lol

I think it's **** to be honest and hopefully as it matures it will get better.

I just recently bought an XFX 7850. I wiped all of the drivers off of my pc, downloaded Asus GPU Tweak, and downloaded the 12.4 Beta Display Drivers (but nothing else, so no CCC). However, when I go to advanced mode in GPUTweak, I can check the Overclocking Enhancement thing, but I don't have an option to change the voltage. The voltage doesn't even show up on the screen (next to GPU Clock, Memory Clock, and Fan Speed.) Any ideas why this would happening and how I could make the Voltage adjustable?

this mean voltage is fix. You can't adjust it. Same with my powercolor 7850 pcs+ here. Luckly the powercolor voltage is 1219,0 mV by default and I'm able to run it with 1200/5900 stable.

Guys I was able to flash my Powercolor 7850 to an Asus and my voltage is now unlocked.

My card is stable at 1260mhz on the core and 5600mhz on the memory. Is that good? I'm at 1.3v.

Flashing is still risky but I did it and everything works great.

I used atiflash.exe from a dos usb key drive.

I typed:

atiflash -p -f 0 asus.rom

Just replace "asus.rom" with whatever rom you're using.

Remember this is risky if you're doing it! It worked for me but it might not work for you!
