Added. Option to use lower resolution textures for cockpit and cargo hold (via Special options menu)

 

Activating the new Medium cockpit Medium Cargo hold texture option still exceeds a 16GB VRAM buffer in the Afghanistan Runway Start Instant Action mission, which makes this new option pretty much useless. Setting Medium textures in the main DCS menu doesn't, so something is going on here:

You can see the stuttering for yourself as the sim constantly has to swap textures between VRAM and system memory. Keeping this special option off and using High texture quality in the main DCS menu (which I can use for any other module) results in even lower framerates and more stuttering. Medium runs fine.
It is however annoying to have to dig into the menu options to reduce texture quality for just this one module.

And for those who are wondering: this is after a fresh boot without anything unnecessary running in the background.

This actually might have been a driver bug: disabling ReBAR and then enabling it again fixed it. I'll leave this open instead of deleting it in case it helps anyone else.

I had this same problem today with the AH-64D Sinai Take-off IA mission (which had always worked just fine but suddenly became unplayable with just 21 fps) until this disabling/re-enabling of ReBAR.
