it's for turn off the Smooth Rendering.
Try to uninstall everything (including manually deleting TE2013 folder) & reinstall everything ; it solved some lagging issues for other players => topic5-28542.php
Yes i did it, and then found best settings, and now game running not bad, but not perfect, anyway better
Fullscreen, Vsync off
Smooth rendering On
But im not sure about DirectX ver 7 or 9. With 7 game looks bit simpler and smoother, but with 9 more bright and bit slower.. But im not sure, really.
And after reinstall i got once issue with sun, sometimes my player was in shadow, and ball also.. so I didnt see well, but sometimes, im not sure, but after change sides - everything was better. But just after restarting the game, Ive not seen this more. Also like Forcesun and 1 and 0 nothing changed in file profilename.ini
