KFLL vram

[mataus]

Hi.

I have an issue with KFLL which seems to have occurred only since upgrading from 5.2 to 5.3 (and 5.3HF1UP1). I have a fairly high end system and run with most settings very high, which never gives me any issues. However, KFLL is now using 9.9Gb of my 10Gb of VRAM and causing CTDs.

I used to have no issues flying in or out of KFLL (PBR version), but I hadn’t used the airport for a few months. My flight was into KFLL and at about 10nm from the coast I had an out of memory error. After some trouble shooting, my conclusion is it’s the airport.

Removing all add-ons, I get 3-4gb of usage around Florida. With my add-ons it’s usually around 6-7 (this is with activesky running, FSLabs and ORBX vector etc). I run with frames unlocked, 60hz and half adaptive refresh rate. This gives a steady 30fps with few lags or stutters.

With LatnVFR Miami (with city active), I get a steady 6.7gb if usage. As soon as I load KFLL I get 8.8gb and then it climbs to 9.9gb. I dropped my textures from 4086 to 2028, but this made no difference. I’ve spent a week testing all my other add-on airports (over 300) and KFLL is the only one that causes this issue.

Any ideas or help?

Win 10 Pro
11900k @ 5.3 (HT off)
32gb ram
MSI 2080ti
Multiple m.2 and SSD drives

can you first try this:

furthermore, there is a non-pbr version of KFLL and KMIA, have you tried?

Thanks for the reply.

So after some testing, the only way I can avoid a vram oom and keep the PBR KFLL (bought it especially for the slope) is to have the non-PBR KMIA installed and reduced the autogen to medium.

Doing test flights between KMIA and KFLL I still get VRAM usage as high as 9.0, but no CTDs. I tried changing autogen from high to medium once the flight was loaded, but this made little difference to the high vram usage. I’ll just have to try and remember to lower it before starting any flights into KFLL.
