I have now tweaked them to higher quality settings, i have been able to reduce the blur and "grains" in the graphic originally these were my settings:
Aspect Ratio:Auto
Anti-Aliasing: 2x
Screen refresh rate: 60hz (this i haven't changed)
Sync ever frame: no
Shadows: no
Spectacular map and depth of field:yes
Ambient occlusion: off
Bullet impact:yes
Soften smoke edges:yes
Image quality: high
texture quality was auto
After increasing the quality there has been a profound impact.
Thanks
