hi Godfella, again, update drivers for graphic card. Then, find and delete
gta_sa.set (you can find it in My Documents folder. This will erase all your configus). Try to run in compatibilty mode (Windows 98) and/or lower resolution and detail. Also set the
frame limiter to off.
If you can't buy a new pc, try to ask some friend or someone you trust. I personally have never spent a euro for the pc's i own. I always asked for and found. If you do not have too many claims you can find a good pc, or the parts to assemble
