    It's interesting to note that StarCraft 2 is far from the only game that exhibits that problem, so anyone using this should be wary. Many games lack framelimiting in the menus or loading screens (or any time when the game world is not being rendered).

    Crysis, for instance, doesn't seem to limit frames while in the menu or loading screens. I can see the framerate jumping up to just under 1000fps on my GTX275 at the menus in Crysis and all the way until it gets in-game. Not that I need to see it, as my GTX275 tends to capacitor-squeal when working like crazy.

    Many other games exhibit this behaviour, so players be warned - StarCraft 2 isn't the only game that could drive a GTX580 crazy with this hack. :)

    Cue a malware writting ejit thinking wouldn't it be fun to write this into his latest trojan as a immediate executable when a gtx580 is detected!

    As you say, Zurechial, Starcraft 2 isn't the only game that causes the GPUs to 'overwork' in menus - Magic: the Gathering: Duels of the Planeswalkers does the same if Vsync is disabled. I imagine lots of others do, too, but I tend to run with Vsync forced on, as tearing (even a little bit) drives me up the wall...

    Batman AA is another game that uses no frame limiter in the menu or pause screen.
    Notice how your GPU fan spins like no tomorrow in the menu or when you pause the game, while in the game, where you would think you stress the GPU, the fan is fairly quiet in comparison.

    Nobody else noticed this is comfortably outside ATX spec?

    Can we tweak it so it'll go to say, 300W?

    So what exactly does this thing do? It just limits the maximum power draw? Is there any performance gain to be had? And how will you supply a card with 350 Watt?! PCI-E slots give you75 Watt, each 8-pin connector another 150. That adds up to 375... pretty close if you ask me. Unless they added a 3rd 8-pin that I missed.

    As the article says, there's no benefit to this modification with real-life usage, only with benchmarks. It could be useful with OCing, but you would risk burning out the card/mainboard any time you hit something like that non-framerate limited menu of SC2 :)

    hasn't that been patched yet?

    150w + 75w + 75w

    8pin + 6 pin + pcie slot

    you'd think something gotta give- water cooling at 350w would probably be a good idea to keep temps down on the gpu

    it's like those 150mph limiters on modern saloons, why would you want to take it off if you are not going to take it on the tracks?

    allowing it is just dangerous, it should only be done by reviewers and extreme overclockers, normal users should not be allowed to have such simple tool.

    I, for one, cannot wait for the GTX 595, with it's "Conservative" 400W limiter, and 6 8-Pin PCI-E connectors.

    Yes. See that wonderful little checkbox labelled "VSync"? Click that and the problems are gone forever.

    Anakha, games should not need to limit their needs to account for poorly designed, power hungry chips.
