Q: I play Resistance on high detail terrain and visibility of about 2500m - which should be of no problem, as I'm playing on very powerful computer. Still performance seems to be very slow, especially in some missions. What can I do?
A: Use lower terrain detail settings (like "Normal"), especially when using increased viewing distance. Terrain detail level "High" requires a lot of memory and CPU resources, and it was included mostly in anticipation of hardware that will be available several years from now.
