Not sure about those, but I know one killer to gameplay in SP/COOP is RAM. Try reducing the number of bots - Until i get my rig up and running, I play with low specs for everything, except effects (Just gosta have my pudding) and with a max of 28 bots total. I used to play with 18, but I needed more squads for the effect
Frankly, anything abover 48 becomes a frag-fest
A DAY LATER - TO AVOID DBL POSTING:
I was playing COOP Luttich, trying to get a better oppinion of the map (The flags' spacing doesn't help since al the space infront of both main bases is useless except as means of getting to the town)... Anyway, I noted something terribly wrong... Bot who spawn at the main base, for some reason STAY there - I know of Americans, not sure of Jerry. They actually idle, which is rare for FH2 bots... I had to TK alot of those bots to get the game moving, since my entire squad had spawned there
Also, sometimes a tank may be taken and remain at the base too... OR it drives towards the church base and drives right off the map and is killed for it. So unless the tanks decide to go south to the 3 other bases (Both town bases and the third one), its rare to have them on the battlefield at all...
