logitec wheel setting the latency help!

I set my latency by trying to get rid of the high frequency oscillations, which occur when you 'disturb' the wheel a little at high speed. I just set damping to zero and changed my latency until these oscillations immediately damp out. In that way I got a latency of 0.103 and it seems to feel good. But I'd also like to know, if that is a correct way to set the latency and if someone had invented other ways of doing it. (Comments from the pro's, please...) And, yes, the higher you set the latency the more 'bumps' and 'twitches' you get, especially near the center of the wheel when you do minor corrections in straight line. I've noticed, that this becomes worse, if you set the sensitivity of the wheel to 'high' in the profiler. So I run it at 'medium'. Also higher damping (not too high...) does help.

Strange, that you can use such a low latency (like some other people). For me, that just doesn't feel right (although it is much smoother). BTW, which sensitivity are you using (to set in the profiler)? I've tried medium/high now and suddenly the high speed oscillations where back again. I think I must investigate this further...

I've used the same process as you. After more than 60 various combinations, from high latencies of .300 down to .000 I have settled on this setup. Been using it for a week and find it the best for me so far. force_feedback_latency = 0.005 force_feedback_damping = 80.0 max_steering_torque = 220.0 Profile settings: Overall - 150 Spring- 140 Damper- 140 Centering - Off After the kink at Kyalami I can feel the front end load up and then down the hill is a good place to feel the spikes. The .005 latency stopped the spikes with this setup. BobM >I set my latency by trying to get rid of the high frequency oscillations, >which occur when you 'disturb' the wheel a little at high speed.

In the profiler I use med sensitivity and low dead zone. I have the windows joystick deadzone set to 1. I don't think there is a "correct setting". I kept trying to get rid of the spikes and still be able to feel the front end as much as possible. After so many combinations I have settled on my present setup.

I have another problem. Now i can not use my joystick. For some reason windows thinks it is disconnected. I even unplugged the logitec usb wheel. What can i do?

I followed all of the other settings in this thread, but I can't figure out what you mean by "I have the windows joystick deadzone set to 1". Thanks, Gene

dinput.dll controls the amount of play(deadzone) at the center of your controller. The default is 5 which is usually fine for a joystick. Most guys find that it is too much play for a wheel however. I use http://home.att.net/~stickworks/ctfjv320.zip to set mine to 1. You can also find DXTweak at http://www.wingmanteam.com/Latest_Software/Gadgets/gadgets.htm . It will do the same thing. BobM

I do not get this. does it mean the deadzone setting in the controller of logitech does not override the dinput.dll defaults ? Then why is it optional ? sandor
