Input lag in menu War Thunder

sorry to add this here but I can’t give this thread anywhere else

I am experiencing big problems with the game, well I enter the game and I have a hub often happens input lag when selecting a vehicle, my computer is not a potato because I have i3-13gen,16GB ram, 8GB Vram and rtx 4060 the game is on max, this error happens only in the hub, it is such a bug where with input lag I have to wait even 15-30 seconds and then I see the game processing in quite low quality and after a while it goes back to max, I tried lowering the graphics settings but this bug repeats, during the game I experienced only one input lag.

Assuming you are on PC and not laptop?

With your current CPU & GPU config you are running at a bottleneck exceeding 20% average and this will increase with GPU heavy tasks.

As a baseline I would suggest eliminating GPU accelerated tasks like Discord overlay, Discord hardware acceleration (if you are using discord), close background apps like streaming sites, etc.
If you are running DX12 with DLSS I would also suggest reverting back to DX11.
If you are using a resolution exceeding 1080p I would also suggest scaling back to 1080p.
Ensure that all your drivers are up to date.

Tech-nerd wise - Your CPU decides what needs to be done and then sends it to your GPU to draw the picture. In your current situation the i3 is a bit slow comparing to your GPU and most likely is not sending your GPU the draw-queue fast enough.
