Lower framerate because of new wheel???

I upgraded today from my old Logitech Driving Force to a new Logitech G 27!
But now I have less FPS!? The only thing I changed was the new wheel...
Is it possible that the new wheel has more demanding FFB and therefore I get lower framerate?
Do I have to turn down the graphics options or do you think there must be another reason?
Perhaps there is a conflict because of wrong controller-settings?
All I did was a fresh reinstallation of logitech-software for the G27. In the Logitech-Profiler I did nothing and in game there was already a profile for the G27 wheel so I did also nothing.
A: Any ideas concerning the framerate-drops (from 60 FPS to 50-60 FPS)?
B: How can I lock the G27-wheel? I have 900 degrees but some cars have less degrees. In this case on screen the rotation stops if it has reached maximum but my G27 wheel can rotate further...
C: Is it okay that I left all the settings in profiler and in-game or should I change something?

 

I have never heard of a wheel being any kind of related to FPS...two titans only gets you 60...that sure doesn't sound right...anyways here is a thread you will want to read through: http://www.racedepartment.com/forum/threads/assetto-corsa-logitech-g25-g27-settings.77244/

 

Maybe your G27 is drawing more resources than your DF used to, but surely that would be more dependent on cpu than gpu.

Might be worth setting your G27 software and AC exe to run on high priority and see if it makes a difference. I know it's a bit of a noobie trick which can cause instability, but I noticed a decent improvement when I did this and have not experienced any problems so far.

 

I would turn off v-sync and see what kind of FPS you are getting uncapped.....it should be 70+ with that setup....then I would cap them at 63.....There is no reason in the world one wheel would ever cost you more frames than another...especially going from a DFP to a G27. It really sounds like you might have a virus running in the background; something is far from correct.

 

Yeah... but look at his sig 59x10 @144Hz + Vsync on.

Looks more like he's not able to keep up with that refresh rate.

 

You think 70+ should be normal with my setup? Did you consider that I play in 3D-surround? 3D-vision usually costs 50% of the framerate but that's the reason for the two titans. I really NEED 3D meanwhile because it feels so much more real if you see the corners coming... ;-)

 

I had the tech preview set up in 3d on my system...a real ***** using AMD cards...it was awesome and I can see how you wouldn't want to be without it.

For 3d I would turn off v-sync (nothing good ever comes from v-sync in racing games) and manually cap the frames at 120. Set cubemaps to low and do not use the lap timing app (it eats massive frames on crossfire and sli setups) There is a mini lap time app over at race department that takes up far less screen and uses next to no frames.

try that and see what happens...you might have to set shadows to medium but probably not...that is a power hungry system but if two titans can't do it nothing will.

 

Does anyone have an answer to my above question B?
Is it possible with the Logitech G27 wheel to have a hard steering-lock (done by the force feedback motors) if I drive a car with less than 900 degrees rotation (for example if I drive a car with 300 degrees rotation my Logitech wheel should also lock at 300 degrees...)?
