Hello @NeoXX this is to us to all famously your hardware isquite rather good, however, for it your hardware is not able to do one few Fps agrees in the multiplayer as in the singleplayer. The problem is the Euro Truck Simulator 2 plays is there on single player optimised and where the play on Mark has appeared there was not the multiplayer at all. In the multiplayer must load he everyplayer what mixes one in achievement takes away.
I have a GTX 980 and as soon as I in Rotterdam am with one player mixes number mine decrease fps up to, less than, 20. I hope you Understand! Sry for my English!
