Check your Terrain Textures setting

[Mr_sukebe]

Just a suggestion from my side.

My opinion based upon testing is that Terrain Textures set to High is a very fast way to overload the VRAM requirement of my 3080ti.

I’ve been running with Terrain Textures set to Low for months.  I was still surprised to see that the most recent update reset the setting back to High.

I’d like to recommend that unless you’ve a GPU with 24GB of VRAM that your confirm for yourself by testing with each of the options and then set as you see fit, just ensure that you check it post further updates.

I wonder if preload radius affects it. On a 3070 I always had issues with VRAM on high, especially replaying a mission without restarting DCS.

On a 4090 no issues

It's a pity we don't have an medium setting for ground textures. High eats up all your VRAM and low looks really ugly.

I have an rtx 4070 and am not noticing any VRAM issues. I have terrain textures set to high and preload at maximum and I get steady frame rates. I wonder why VRAM overload is such a variable factor that affects one users and not others? I only play SP so maybe more of an MP issue? Is it worth trying a like by like comparison? I know this is not very scientific given so many variables but it might be possible to fix some factors as a form of standardization.

The VRAM usage is dependent of terrain texture and visib range.

With the 3080ti, high terrain texture and medium visib range is OK but increasing visib range to high or more pushes the VRAM usage near 11Go

I have visible range set to extreme and I have steady frame rates. VRAM is just below 11gb. How would VRAM overflow manifest?

In my case is a combination of module and settings. With F-15E I always get a VRAM issue which can be resolved with switching to F-10, Alt-Tab and back. No issues with other modules (with Oculus Link)

And now that I'm using the laptop, the F-15 is unplayable no matter the settings or tricks. Other modules are above 36 FPS (no ASW) with my laptop and moderate DCS settings. 

Only case I get it working is with Virtual Desktop
