NBA 2k13 FPS Drops

Hi Guys!! I'm having a serious problem with 2k13, during the matches, the fps drops, buts just for a few seconds. I've read that some people had the same problem and they solved it with a few changes on the config file. Well, I've tried that a lot of times, changin most of all the CLOATH_LOGICAL_THREAT, but generally there was no changes on fps drops. I wonder if someone can help me with this, beucase i have a good pc for this game but i cant play it at 100%.

My specs are :
-AMD FX 4100 Quad Core 3.60 GhZ
-4 GB Ram
-Ati Radeon HD 6670 Gddr5 1 GB

P.S: I'm From Argentina, Sorry for my english

C'mon guys, can anybody help me with this???

Delete your config file. The game should recreate it. Turn off any anti aliasing in your video card control panel. Add an exception to your anti virus for nba2k13's game directory and the nba2k13 saves folders. Defrag your hard drives. Set the priority for nba2k13.exe to high in the task manager.

i had a similar problem, probably caused by over-heating... i cleared the vents from dust and downloaded speedfan to check the temp's. now everything is working perfectly!

Some time ago i did realize that ventilation was the problem,i bought two coolers for the cpu an for sometime the game was ok, but after a while it crashed again, so i cleaned it but the problem remains, maybe its the case, that don't have a very good ventilation, i'll have to change it, thanks man.
