Bad performance on custom campaigns
Hi there, I started playing some custom campaigns a few days ago and most of the campaigns are not playable.
I have to admit that my PC is really old nowadays, it's just an amd x2 4200+, 2 gb of ram and an amd radeon 4670. The fact is that on the normal maps and campaigns I still play very well with medium settings, running the game ad 1280*1024, I'm always on the 40-50 fps and I get down on the 20-25 when there are mamy zombies on the screen. But with the custom campaigns, for example One 4 Nine or back to school I cannot play, the game is stuttering from the first moment I enter in the map.
Anyone can help? I deactivated any other addon but it's still the same...
