I play on a terrible computer and this shit has helped me double my fps from 20 to 40.
I play on all lowest settings except for my resolution, which is at 1080p.
If anyone who's good at this could tell me what to add/remove to get more fps it would be GREATLY appreciated.
Sensitivity: 2.00 in-game sense, 1400 DPI. (yeah I know it's "high")
Launch options: -high -freq 75 -d3d9ex -nojoy -threads 2 -novid +mat_queue_mode 2 +exec autoexec.cfg +cl_forcepreload 1
Autoexec as of right now: https://pastebin.com/rVQux7um (pastebin makes it easier for people to check out your cfg without having to get on their computer and download it 
)
You may notice in the autoexec there is 3 crosshairs.
xhair1: https://pastebin.com/StUfkstW (my old dot crosshair)
xhair2: https://pastebin.com/jHt40F78 (the crosshair I use now, originally made it because dot crosshair was too big on 720p, which I thought would be a low enough resolution to play danger zone with decent fps, but after going back to 1080p with this crosshair still on I really liked it)
xhair3: https://pastebin.com/TU1RrwCf (the crosshair I use to play danger zone with decent fps at 800x600 resolution)
IMPORTANT BIND FOR ALL 10MANNERS:
alias scrim "password scrim123; connect 216.52.148.183:27015"
(once you have this in your autoexec, just type scrim in console and it'll make you join the scrim server)
This command below makes net_graph (the thing that shows fps and shit) appear only when you open up the scoreboard:
net_graph 1
alias -scorenet "-showscores; net_graphheight 9999"
alias +scorenet "+showscores; net_graphheight 0"
bind tab +scorenet
This command below allows a noob like me who uses scrollwheel to switch weapons to be able to also change my scrollwheel to jump:
bind "o" "bind mwheelup invprev; bind mwheeldown invnext"
bind "p" "bind mwheeldown +jump; bind mwheelup +jump"
There's a lot of chat binds and server binds in there so just ignore those I guess.
Having something like echo "AUTOEXEC SUCCESSFULLY LOADED" at the end of your autoexec is fun to have just so you know it worked. It usually does, so it's really just cosmetic for me.
Here's a direct download to my autoexec:
