Hello,

This isn't a forge issue. It's a driver issue. Reinstall your graphics drivers.

In total, how much memory does your computer have?

If you think of RAM, I've got 1GB DDR 2. On my C: Disk I have 7.5GB out of 48GB.

Thank you so much! It worked for me! I updated my drivers! I haven't played Minecraft for weeks! THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU

Just a note you may run into some other issues as well with that low amount of ram, You typically want to keep a few hunder megs for your OS, and ~128MB for your video card {which since this is java isnt included in the heap space} So if you have 1GB of RAM, I would only advise allocating ~768MB to Minecraft, or well getting more ram

I already set it to 1GB, I put all of it for Minecraft. I also got 12GB of virtual memory (I don't know if that does something).

And a another question : Will Minecraft run faster when I set it to 768MB?I got 52 mods, and I got around 100-170 fps (I got the fps plus mod).
