Game graphic get worse after few seconds of spawning

Hi i gave a problem that when i spawn my graphic looks all nice and vibrant and after few seconds it get faded slightly. It happens every time i spawn in ground vehicle and sometimes in plane but i rarely notice that. Does this happend to anyone else and any idea how to fix it.

That looks like a HDR setting that is getting changed or having issues.
Are you using a HDR monitor/HDR settings in game/ HDR settings in windows?

no i dont have HDR monitor.

Do you still have the HDR settings on by accident? (Either in-game or in operating system).

It could also have something to do with post FX settings as they could give a similar difference in looks with Dynamic Lut on/off.

i dont have HDR on in windows or in game
