Switching from Fullscreen to Windowed (Fullscreen) worked for me. Thanks a lot for the suggestion, it didn't even cross my mind once to try it out, so again, thanks a lot.

Sorry, but going back to old drivers are not a solution, more like a hotfix, and a hotfix that can cause problems with other software to boot.

IMPORTANT UPDATE: The situation was fixed by switching from Fullscreen to Windowes (Fullscreen). Hi guys, I just got back to the game after 4 years, and I remembered it as awesome, so I payed for a month's sub to get the full experience from the get-go. Now when I play, I find that I constantly get graphic-stuttering, as if the game is lagging, but the ping is between 45-50 ms, so it can't be that. I have a high-end machine with a fast, cabled connection, so I know it's not those, so I'm thinking its a performance/optimization/campatibility issue from the games' end. These are my specs: ISP Stofa 100/50 Mbit (Cabled) Operating System Windows 10 Pro 64-bit CPU Intel Core i7 3820 @ 3.60GHz 32 °C Sandy Bridge-E 32nm Technology RAM 20,0GB DDR3 @ 666MHz (9-9-9-24) Motherboard Gigabyte Technology Co.

I have a similar setup, and it stutters badly for me too. Wouldn't say it's unplayable but it surely is bad.
