Vsync should not affect mouse's motion in any way. LFS tried to update physics every 1/100th second regardless of the framerate. It's logical to assume that it reads the controls input at the same rate. Cap framerate to 60Hz and turn VSync off and see if the feeling of strange mouse motion persists.

Mmm I just tried it with a cap at 58FPS and VSync off... it does indeed feel the same as when limited to 100FPS. So it's really only enabling VSync that makes the mouse motion feel strange.

Quote from Whiskey :

LFS gets your mouse input for each frame.

If your game runs at 100FPS you get 100 steering updates per second, if you limit it to 59 you are losing precision.

PS: I hope you understand me, it's not easy to explain

Ha... I had thought about this but thought it wouldn't be that noticeable. Well... I'm turning off vsync then because the tearing doesn't bother me as much as losing steering precision.

Hello all,

With my old computer and CRT monitor, I always turned the vertical sync on. Now that I have a new one with TFT-LCD, I kept the vsync off and the fps limiter on 100. Playing LFS with a mouse and these settings works like a charm for me.

But the odd thing is that when I turn vsync on again (59HZ apparently for my iiyama ProLite E2410HDSD) it feels as if the mouse sensitivity changes! It's so noticeable that I doubt it is caused by the game state being 40 frames per second more.

Does anyone have a clue as to why turning only the vsync on would have such a great effect on the mouse control?

Thanks in advance,
kind regards,

Zosma
