I do not have this issue in SP, but while in MP I have random lag spikes every 10 seconds or so. My FPS will drop 20-30 frames for just a second and return to normal. We have tried to uninstall truckers MP and when reinstalled had the same issue. We downgraded the graphics of the game, and still the FPS issues are still there. Any other suggestions to why my FPS is doing this? It makes playing MP with my buddies terrible.
