Title: Strange gpu noise when starting lwjgl programs
Post by: dragomir92 on January 22, 2012, 08:25:38

Hi,

When I start any program using lwjgl (e.g. Minecraft, or even those from the basics tutorial) my GPU starts emitting a strange sound, like screeching.
It's a passive cooled GPU, so it can't be any fan problems. I've also installed the latest drivers without success.

I'm running an EN9600GT SILENT.

Thanks in advance for any tips causing this and how to fix it.

This is usually caused by not having vsync enabled and running a very simple rendering loop (at ~1000 or more fps). This has been known to cause GPU damage for lots of users (e.g. at WoW's loading screen). As a workaround, you could force vsync in your driver settings.

Thanks a lot. That did the trick.
Luckily it doesn't seem to have caused any damage yet ^^.
