i've found that funny guy named oscuro can't go through teleporters, so he always stays in monsters cells and can't kick player's ass. and please, please-please remove that annoying delay between keypress and firing from some weapons. it is not normally if you try to shoot and need to wait 0.2 or 0.5 seconds before shooting. weapons must fire instantly. i think. with a hope for understanding
Terra, googling is the common and preliminary way to find a solution in many (huge amount of) cases. your system specs could be easily get by any sysinfo program like MsInfo64 (u can type it in cmdline) or AIDA64. 4GB\2GB vram sounds like "my sportcar is red and nice" ))
switching off some programs could help to determinate and isolate faulty node of the system. (switching on\off different graphic settings and others). and to determinate what faulty node is : program, service, some settings.
Forgive my tediousness
