CFG annoying problems

[Scarhand]

Firstly, never just do a plug and play with cfgs. You should always make your own, always. One reason being, you get crazy settings like this, it will add things like m_pitch and mouse acceleration which are bad themselves but even worse if not fine tuned to your playing style, and most importantly, some cfgs for download may contain wallhack/aimbot cvars which will cause PunkBuster to ban you just for having that cfg, without even having a cheat installed. That cfg does attempt to set cheat protected cvars to 0, but hardcoded protection will keep those at 1 and prevent a PB ban unless you have a cvar unlocker, but there might be things I overlooked. Here is a website that will check for *most* cheat cvars in the cfg, and is a must if you ever download a cfg (which you should never do):

I did a check and it found no cheat cvars. However, as I mentioned before it attempts to disable some cheat protected cvars though and contains cvars not existing in ET which can make you profile.cfg too large to run and may lead to chronic settings deletion if not using an autoexec.

For the light, muzzleflash is off. I think jaymod uses cg_muzzleflash or cg_drawmuzzleflash, try cg_drawmuzzleflash 0 or may try etpub's cvar, cg_nomuzzleflash. You might be referring to dynamic light, in which case you need to set r_dynamic light to 0.
Daredevil is correct about snaps. It would be set to the same thing as sv_fps which will always be 20 or the server might break. 40 will do nothing at best. I don't know how it happened, but pretty much everyone who knows scripting/cvar basics thinks snaps 40 helps; it doesn't.
The console spamming is from b_logbanners 1. Set this to 0 in the cfg to fix it.

I cannot stress how much I recommend you never take someone else's cfg. You should always, always, make your own. If you have time, here are some places where you can get some info on scripting and cvars, but I wont mention and common (and lesser known) tweaks and scripts that may be of use, find them on your own.
