Well, after testing the game for 2 days, i can say that the problem is still there. If it is true that now I'm better than before, and some maps that before were impossible to play, now work pretty fine. But, some other maps work really bad.
At one moment, during playing in a map, the game started to drop fps (at first it had an average of 60-50 and then dropped to 10-20). In that case, the problem could be also a leak of memory, don't you think?
Ok, any idea to solve this or figure out what the problem is, is welcome.
Thank you again guys.
It could be your video card.
I have a Radeon X1600 Pro and for the most part NS plays very well.
However some maps for whatever reason I see BSP holes on certain parts of the map. A BSP hole is when theres an area on a wall where all the colors on the screen seem to combine together and you get a 'hall of mirrors' effect.
It could just be that your video card isn't handling the information correctly/efficiently and its lagging your game.
