Lag issues in graal

[darius_p2p]

Hey, While I am playing graal, I am getting alot of lag or skippy framerates. This happened literality over night. I did not download anything new on my computer or anything like that. Here are my computer specs:

Processor Intel® Core™2 Duo Processor T7500

2.2GHz, FSB: 800MHz, 4MB L2 Cache

Memory 2GB (2 x 1GB) DDR2 667 MHz SDRAM

Video Graphics & Memory NVIDIA GeForceGo 8600M GT GPU
256 MB GDDR3 Physical VRAM
Direct X 10 Support

HDD 2.5" 9.5mm HDD, 160 GB (5400rpm)

I tried everything from virus scanning and disk defragmenting

Also I tested graal on my older computer, and everything was fine, even through my older computer is much worse. If it helps my old computer is running on a athlon 64 x2 and a radeon x1600
Thanks in advance and I hope this problem can be fixed!
