My harware is as follows: MSI Z390 MEG ACE motherboard, I9 9900K CPU, 64 gb G. Skill TridantZ ram, and RX580 (8GB) GPU. The GPU I have been using for a long time to play Freelancer Discovery, the motherboard, CPU, and Ram are new to Freelancer Discovery.
Also, when I get kicked there is no message from server, so it is probably not related to anti-cheat. Direct Play is enabled. I tried changing the desktop resolution but it had no effect. the resolution in game remained the same but did not match the visuals. Visuals were of a much lower resolution. As far as the file DSAce.log, I did not find anythinging unusual there. The resolution in the file matched my desktop. Will try other stuff that you mentioned and will get back to you.
