Got issues with delag, fps, high detailed textures?
No matter what hardware you have, you will have performance based and optimum settings. Graphics cards also tend to mislead people as they are likley to be more complex and don't really give you advantage. All the maps and images are loaded before starting so any problems will likely to be config based.
This info may help, the config tweaks in the file section may save you time.
Some people seem to be confused between delag correction but if you have problems with aim then you will be wasting your time messing with any network based settings - unless you are already using basic display settings.
To confirm, just up the splash radius and most times people will say right away their network is much better :D Sometimes truth hurts and there are other fixes that just makes everyone happy :D
The model textures on OA compared to default team models also affect accuracy. This doesnt necessarily mean the models dont work correctly or they are poorly designed (although i dont see the point of have seperate files for eye colors - wtf). It's all about performance vs quality again :D
