This is a problem with FPSC...When the FPS is high, the frames for the guns still move at the same pace... Think of it this way:
A gun has a 10 frame long reload animation.
At 10 FPS, it'll reload in 1 second.
At 20 FPS, it'll reload in 1/2 of a second.
At 40 FPS, it'll reload in 1/4 of a second.
Therefore, if you have a level with variable FPS, it'll make it so that it reloads faster with higher FPS's.
However, stuff like Fenix Mod use a timer system to keep it smooth...So no matter what the FPS is, it'll take the same amount of time to reload. So I'd reccommend getting something like that.
Hope that helped.
