Lag when firing weapons

[comte]

When I first load a scenario there is lag when I fire a weapon type for the first time after this first firing there is no lag. This is pretty annoying.

Probably, like in PzC, sound and animations are loaded from the disk on the first time you used them.
After the first use they are cached in the ram, so they are faster.
Could you attach a DxDiag report file?

If you have anti-virus/security software, it's also possible that is causing some lag. Try disabling it and see if it makes a difference.

I own Panzer corps and have no problems at all running it no lag at all. I am using a laptop.
