Wow. I had the worst potato lag today. Got on about 12 hours ago on EU 2 when there's about 4,100 on. I spawned at my garage in Katowice. There were up to 15 others in proximity. For 45 minutes, only 2 of those players loaded in while the rest were still 0.0m. So i'm just driving around the garage trying not to get AFK Kicked and my game decides to let me drive a bit, goes "guh", drive, "guh", ect for the entire duration. Besides upgrading to a something that can play the game without any problem, does anyone have any suggestions?
