So, today I talked to someone who was using very similar pc setup as me, but he was able to run 40 clients and only using around 20% of the CPU.
I on the other hand can run 20 clients and have my cpu maxed out.
Now, I have my gfx settings turned all the way down, but he said he made changes to his config.wtf in which he reduces those settings even more.
I tried playing around with it, but I got no change to my performance.

Does anyone have experience with the config.wtf?

Any help would be appreciated.
Thanks
