Hey guys, i am currently playing on a old computer, but even with the LOWEST settings in the menu,with 800x600 resolution, i have alot of freeze / lag ...

1gb ram
NVIDIA GeForce 6100 nForce 405 (512 Mo)
DualCore AMD Athlon 64 X2, 2100 MHz (10.5 x 200) 4000+

is there something possible to do ? or just surrender ?

There's no way your computer can't handle the game, not with those specifics. This game's engine was written in 2003 and could be run @ 1000 MHz and GeForce 2 with 64 MB.

Your OS is just probably full of useless garbate that takes the resources in the background.
