AFAIK it is possible to assign mouse to "Steer Left/Right" control in joy/wheel setup screen. I've done that when I was a mouse driver since I played with steer degrees (and steer compensation=0) in order to obtain more precision from mouse.
I often race with mouse + pedals. Sometimes i really cant be bothered putting the wheel on the desk. It takes less than 2 seconds to switch between wheel and mouse in LFS. The only real downside to using a mouse to steer is correcting slides can be a real pain in the ass.
what pedals do you use anyway? can you help me how to combine my momo with mouse?
i find by using mouse + keyboard my laptimes was better than using steering wheel, also i can play as long as i want without feeling dead tired after using steering wheel for 1 hour
