Steps for reproducing this issue:

In windows client i have normal hitbox. Fore example from AK i make 70-90 damage from 2-3 shots. In linux client usual i make 5-7 shots from AK, but only 1-2 of them passes, and make 18-27 damage. After migrating from linux to windows i have ranked up from gold nova 1 to gold nova 4 in 2 days. And yesterday when i played on linux again, i saw this difference again.

After last update hitbox became much better. But sometimes i make 6 hp from 2 hits with a rifle. And after 3-5 matches i have lover hitbox, maybe because of driver for the network card (from linux core).
