Small lags every few seconds with controller input

[unairspace]

Hey guys,

 

I have this issue almost every time I play (both online or offline missions) that with controller input (X, Y, Z axis), there are lags every few seconds. If I leave the controller with no input like under autopilot mode, the game is running nice and smooth, as soon as I touch the stick or throttle lags come back.

 

I have no prove that this is 100% caused by controller because I get lags free experience

say 2 times out of 10 which confuse me.

 

Need some helps here, thanks.

 

My rig: i7 8700K, GTX1080ti, 16GB memory, Win 10 pro+X-55 controller (workable driver version, working fine under P3D)

I did some test flight today with FPS display on.

With no control input the sim maintains a steady 60fps. After take off (UH-1) with controller input, lags come in, with 1-2 second of time interval FPS drops to 45-50 very quickly and then back to 60, and then drop and then back.

 

I tired delete the shader folder and the sim runs very smooth for the first 5-10 minutes and then lags come back again.

It could be USB driver related, I guess? Or USB power savings feature? Maybe try disabling the microphone and network card? Some have seen improvements. You can also use process explorer to see what files/services coincide with the lag.

 

Or maybe using a USB card that shares PCI lanes with the video card? (that last one, I'm grasping at straws)

 

Finally, use GPU-Z to make sure your PCI is using gen 3 @ 16x.
