Needs GPU VRAM Optimization

Featured Replies

Now that I have had a chance to test the update:

1. On my machine (AMD 5800x, 32GB, 6700 xt, PCIE4 SSD) - the popins are sometimes present but not that bad.

2. Changing left / right snap view to pan view helps.

3. The sim is pretty good but needs VRAM optimization. It was only using around 4GB of 12GB.  If it was optimized to use an extra 7-8 GB VRAM with trees and buildings etc there would be no such popin issues, and scenery would look more dense.

4. The instruments are much smoother 👍

5. Good update overall.

Did you try to push the LOD further from the UserCfg.opt file?

I am testing with the Vanilla install right now (no mods).

Push it further, with the new SU5 we were able to push it further to 4.0 or even 6.0 😄. Asobo should really unlock the sliders but I think they will do sooner or later anyway

You are looking at it the wrong way: They decided to NOT draw the trees, buildings out-of-sight to reduce VRAM usage. VRAM is a problem for most users, even for myself with my 11 GB card; on DX 12 it would have become a major problem (P3D docet).

Apart from that, the extra trees, buildings etc. would not only use VRAM, but also CPU power, which would bring us back to pre-SU5 performance. So VRAM IS actually optimized.

Wrong.

VRAM should be optimized for all installations. Depending on the complexity of scenery and aircraft and weather etc, VRAM usage should be optimized to use close to 100%.

It should not be that users have to tweak config files. The scenery loading should be optimized per hardware (available VRAM).

So you want MSFS to draw some fake trees and buildings in the Sahara just because the sand doesn't fill up VRAM enough on my (hypothetical) 22 GB card?

Nope, it should use a maximum VRAM usage up to 99-100% as per scenery, aircraft and weather situation.  4GB may be appropriate over desert!

Should it also use 99% RAM?

No - computer RAM is different.  I think that has been optimized in the latest update.  Lower computer RAM is always better.   But GPU RAM should ideally be close to 100% in dense areas.

I could not make this  "boo" up....😄

Expanding the LOD will give you better tree distance, but what i have experience it will look even worse, because you will see it drawing longer out as the pop ins will start from the same close distance no matter which lod setting you use.

Sofar I have hardly noticed the popping, even with TrackIR. Only if I suddenly jerk my head to one side I can see the trees pop in place, but it is hardly noticable at least for me with normal head movements.

It may depend on the area one is flying in though. Still it would be nice if we can adjust this from within the sim itself.

If you have a newish video card with GDDR5X or GDDR6 with a good data rate and bandwidth you should be fine, however users with older specs are going to notice the popin's much more.
