Hi, been on the mouse and keyboard for roughtly two months but get my G25 in a bit woooty (well its ordered and on its way). I just thought to myself looking at my replays where do I REALLY lose time because I use the mouse and keyboard, and its quick and easy to spot its because of tight and tightish corners, you cant really have a smooth follow through without just letting your car roll round the corner without throttle.If indeed you do throttle your car will slide about, or spin if your in a rear wheel drive, this is all because that button on my mouse will accelerate full everytime, to get smooth acceleration that is needed to take on a corner, you have to keep tapping the throttle, whereas the people with pedals speed through. You can obviously say; 'Just buy a wheel and pedlas', but in LFS's world I can imagine you need a decent wheel to really enjoy it, something with FFB and even a clutch. Therefore the cost isnt cheap, and I bet many people start to play LFS without a wheel. I suggest this, one simple addition to the keyboard/mouse controls, to allow keyboard/mouse users an at least more controllable throttle. Basically implement another throttle key, one for 50% and one for 100% throttle.

Edit: I did use paragraphs, where have my line breaks gone?

Did you write your post in the alternate edit mode? The little A int he top right corner? If you were just hitting return in an HTML/BBcode editor any formatting wouldn't appear. The background changes to grey in the wrong mode in Firefox.

Anyway, one way you can control keyboard acceleration (I think) is the Button Control Rate setting. IIRC that will slow down the effects of holding the button down. The problem with that is that if you suddenly need to floor the gas or brake quickly, your car won't respond instantly.

I preferred to stick with tapping when I still used the keyboard.

How about a second Kb key for throttle which progressively applies throttle the longer you hold it down, (controlled by a second Button Control Rate setting), maybe with a maximum throttle setting for that button too (eg 50-80% max throttle), that you can have as well as the full on/off option. So you have one button for when you just want max accleration and another for when you need to have part throttle/slowly increasing throttle.

This will become a deja-vu pretty fast.

The idea is that it's a racing sim, best used with a wheel...and that about covers it.

My first wheel cost me £5 from ebay (logitech wingman, yellow and no FFB) and I loved it for over a year and a half until I coughed up for a DFP. It's a lot cheaper and easier to get a fairly decent wheel than you think.

You can already use the mouse y-axis for throttle and brake. The mouse axis can taken in a wheel-setup. You don´t need to have a wheel for using a wheel setup.
