Game tweaks would be up to you and their forums (the Warthunder forums.)
I would try a VPN along with changing your DNS to ones like 126.96.36.199 and 188.8.131.52.
If you are on W10 and run an antivirus suite that has been known to kill network speed.
(originally sent to Warthunder developers. Ran internet test including a trace. It showed Hop 7 and 8 timed out. ISP issue. Century Link tech support didn't have a clue. Any Ideas? Would like to post trace but can't add pictures to here form my files.
"For some reason, and within the last 2 months, I cannot get into the Warthunder game until it is well underway. I am running a dell Alienware gaming laptop. I have a high-end modem and Netgear Nighthawk 8000 router. My internet speed is 100 bps. Firewall is set to allow Warthunder to run in-coming and out-going. I have disabled all programs and apps running in the background. I do not use any customs in my game
The issue appears when the map I am playing on is shown. The map comes up brown, then within 20 seconds the map appears. It then takes quite a long time to leave the game map and get to my base where the tanks are shown so I can choose one. Usually 1 minute. By that time, the game is in full play and I have lost advantage. Once I am in, game play is fine. Any ideas on how I can further tweak to enter games on time?"
