How much vram does FSX use at high resolutions?

Featured Replies

I know at 1080p with a few windows open at a heavy scenery area, FSX only used about 1.1Gig of vram.

 

What does a machine running a high resolution setup use for vram?

I'll partially answer my own question after running many games at 3840x2180 tonight, more than 2 Gig.

 

Time for a 4 Gig card purchase. <sigh>

I use 3 Titans X and I have seen on my system using almost the whole 6 gigs.

I find it hard to believe FSX is using all 6 Gigs at one time. Perhaps nVidia caches the textures some how in the vram for use later on if FSX calls for it?

Not sure how nvidia works but I was surprised too, I think it has to do with my resolution 8022 x 1600. I did a while ago a vid with a  not so heavy scenery and it used  3500/4000.
