ok, halo 3 was awesome, but the bullet holes only lasted for about 2 seconds. I no everyone says 'who cares how long bullet holes last' but it really imroves realism and the general feeling of the game when they stay. And before anyone posts 'but it slows down fps', in the games I have managed to tweak to get bullet holes (and brass as well) to stay, it has had very little effect on fps. SO, I thought it would be good to start a thread where people post (and ask for) tweaks to make bullet holes and brass stay. i'll start off with the following:
Red orchestra: go to config file, change 'mindesiredframerate' to like 10, bullet marks and blood should stay
there is also a line called 'decalstayscale' could try that
ghost recon: brilliant mod made by 'agent smith' google search should help on that one, makes bullet holes stay and a few other minor tweaks
COD UO: managed to find a mod to make brass stay, but ran into some issues. ask me about this one if your interested
ok, these are my only succesful tweaks, am looking for:
COD 4: increase bullet hole limit
HL 2: make brass stay
Farcry 2: bullet holes stay for longer
Farcry 1: brass stays
oh yeah, I tweaked farcry 1 to make bullet holes stay

any questions/helpful comments?

I think you can just use r_decals 200, mp_decals 200 for Source Engine games (You can set the number to however many you want) These allow the number of sprays/bullet holes to appear before they start to disappear.

cheers Absurd, do you know what the max setting is? also, brass and bullet holes are seperate, think brass is a physics object, not a decal. but thanks for post :)
