Blizzard software ate my GPU

Written by Nick Farell

Starcraft II causes overheating problems
Blizzard has admitted that its latest Starcraft II game has a bug which can cause a GPU to go into meltdown.

The game's menu screens aren't framerate-limited which means that if the computer has nothing else to do the graphics hardware gets bored and starts to render the screens. This sounds like a good thing but actually causes overheating problems for the card.

The good news is that it is a doodle to fix. If you go into  "Documents\StarCraft II Beta\variables.txt" "Documents\StarCraft II\variables.txt" file and add in the lines frameratecapglue=30 and frameratecap=60 everything goes much better.

It is strange that while Blizzard have admitted that there is a problem, it has not really notified people about it.  Still it is nice to have a fix and if your GPU has not melted down to China you can probably give it a go.

...with all the time used to polish the game no word of this got to any of the developers?

It'll get patched eventually though really that's a pretty bad bug to RTM.

Speaking of patches if you want to get an idea of how well Blizzard can patch things install a copy of Diablo II 1.0 without the Lord of Destruction expansion pack or any patches. Still companies should release games as if they were unpatchable.

Doesn't this just create a situation where the GPU is at 100% load? As I understand it, a GPU will always render as many frames as it can, pushing the max FPS it can, regardless of any FPS cap (which just limits the number of frames displayed). Running furmark wont melt your gpu if it has adequate cooling, why should this be any different?

That's true , also keep in mind that all modern GPUs have protection against such issues , there is a temp threshold ,after certain temp frequencies go down hence temps... only thing you will notice is reduced FPS

@Fox, actually, the limitation is detected in the driver... if it finds out that the output is only of 60 fps but the render does 200 fps, then the driver slows down the GPU.

Otherwise this wouldn't be a fix and people would still complain about the issue.

The superhot/power hungry Fermi will surely melt.

depends on your case/driver, frequencies stay the same but load gradually goes down depending how hot it gets. heres one for you..some ingenious person at BFG told me to run furmark to see if my card is messed up, I told him avg temps was 107 Celsius within 30 seconds, but thats within "tolerable" range... so i let it run til hes satisfied the cards hot enough to bother with an rma... (topped out at 115 Celsius, horrah that was hot enough for an rma!) but to the point... the hotter it got the gpu load kept goin down to about 40% and barely a few frames a second at that load/temp on 197.45. on a normal card it would probly be okay. BFG just wants proof your card will melt your case and all surround cards before RMA appproval

@blandead

and that's one of the reasons BFG left the graphics card business couple of month ago :P
