Whenever I join a game in Multiplayer and the maps starts to load, when it says "Awaiting Textures" my computer goes to 0 fps and it takes an extra 15-45 seconds before I can finally join the game which causes me to miss the start of the match. 
I have a CyperPowerPC Gamer Ultra 2098. It has an AMD FX-4100 3.6 GHZ Quad Core Proccesor and I upgraded the video card from the AMD Radeon 6670 1GB to the Sapphire Radeon 7850 2GB Overclocked Edition. It passses minimumm and reccomended system requirements and I run the game on ultra settings at 100-140 FPS. So, I have no problem running the game, as you can see, but I have slow loding times. Any suggestions?
