is Intel virtu useless on Battlefield 3 ?

[brandon888]

i have I7 3770 ... IGPU enabled from bios and virtu software is on ... seems like
it does not gives extra fps in BF3 ;/ Yes Hyper performance is enabled to ;/

so is this useless gtx 480 with HD 4000 ? or im doing something wrong ?

I thought the iGPU was mainly for idle/low demand modes.

Did you seriously expect to gain anything by using the iGPU to "help"? The performance difference between it and the GTX 480 is massive, so gains would be barely noticeable. Plus, the whole Virtu thing has a visible overhead.

i just though that HD 4000 will game me like extra 4-5 fps in battlefield on ultra maybe i expected too much never had virtu sorry and IGPU

Doesnt it hurt performance more often than it helps when you use it with a bigger graphics card?

Arkadrel

actually yes ;/ sometimes i even notice worse performance with virtu .... crap ;/ ....

Cuts my performance in half, im using older stuff though.

Using cpu graphics to help a real video card is somewhat akin to trying to thicken ketchup with tomato juice.

Virtual V-Sync: this attempts to remove screen tearing, like normal v-sync, while reducing the penalty to responsiveness from input peripherals (mouse/keyboard).

Hyperformance: uses the integrated GPU on your 3770K to predict what frames aren't going to be displayed, and removes them from being worked on by the discrete GPU. Basically, the dedicated GPU has to work less hard, increasing input responsiveness just like Virtual V-Sync.

These only work when your frame rate is higher than your monitor's refresh rate. This means that if your monitor refreshes at 60Hz (most do), you need a frame rate higher than 60FPS for these to have any effect.

Well, that's how they're supposed to work at least.
