when i set all settings to low resolution to 800x600 and dx7 i have the same framerate as on 1920x1080 and everything on high with dx9
The full 200 Slot Siege Server is with 10-15 fps not playable for me and on battle Servers its really difficult to play sometimes with 25-30 fps.
in mount and musket the battles was never a problem only on siege with 100 players with particle effects i got sometimes arround 40-50 fps but it was ok.
Now i get in siege battles with 100 players average 25-30 fps.
I tried out older drivers and its still the same. When i get time i will try out my old Geforce 275.
