Hi all,

I am incredibly frustrated with MSFS 2024 right now. I used to run it on my 5 year old Predator Helios 300 laptop at pretty much medium settings and was always able to squeeze decent enough performance on all of my aircraft and airports (PMDG, Fenix, MD-11, iniBuilds etc) at pretty much respectable level. It was an ancient laptop with an i7-10750H CPU, 16GB of DDR4 RAM, a 512Gb SSD drive, and an RTX 2060 with 6 GB VRAM. It was running at native 1080p.

I figured it was time to upgrade anyway, so I got myself an MSI Vector laptop with an Intel Core Ultra 7 255HX, 32 GB DDR5 RAM, and a RTX 5070Ti with 12 GB VRAM. And it runs absolutely atrociously! I am running 2x DLSS FG, DLAA, most settings on High, but I even disabled all traffic AND all parked aircraft and vehicles and personnel at the airports and what is killing me is what happens after every landing. During camera panning I get stutters/delays, but the flight itself and the initial taxi at the originating airport are fine. FPS are around 50-90... With PMDG 737 on the last one it was averaging 50 with FG. AS SOON as you touch down in ANY aircraft, be it Fenix, PMDG, iniBuilds, whatever, the frames drop to about 3-4 FPS and it becomes a slide show and I inevitably crash into something because at that point, the aircraft is unresponsive to anything. What is happening? Why? This thing literally has twice the VRAM and a newer CPU, and twice the RAM! I have Raymarching Shadows disabled (and reflections)... Pretty much all settings on High, and this is still an issue. I am absolutely blown away by this.

As a sidenote, I didn't seem to experience it in a laptop I bought a few days ago that died the first night (video card burned out - during software installation of all things! It was literally dead on the first day). That one was Intel Core Ultra 9 275 HX (so a little faster), but only 16GB RAM, and a 5080 with 16GB VRAM...) That one didn't seem to struggle. But there wasn't another one available to exchange for, so I read that 7 is actually not gonna make that much difference against a 9, and 12 GB VRAM should be fine too... plus it only had 16 GB RAM, which to me was more problematic than anything.

Here's the screenshots I took during the last flight and what is happening.

I am not too up to date with computer tech and what's happening, so perhaps someone could demystify this for me and perhaps offer a solution?

I THINK I made some progress with this. It seems the only culprit is Terrain LOD. At 150 it was creating this mess. I lowered to 120 and was able to put most settings between High and Ultra and things seem to be OK so far. Trying a flight with MD-11 right now but so far, everything is smoother. I discovered that by taking a 737 for a pattern on Medium and all was OK. After that I increased everything to High and Ultra and upped the LOD to 120. STILL OK... so, apparently that 30 made a difference?

How on Earth did you run MSFS 2024 on a laptop with only 6GB VRAM??

It was actually fine...

Also, with this one, I think something with LOD settings was off. Cause I was able to increase them back to 150 and it's 80-90 FPS now no problem with BATC and FSLTL traffic injected... So maybe something was messed up in that one setting and it just needed to be changed and then changed back. So weird. 2024 is full of mysteries sometimes.

You inject both BATC and FSLTL traffic at same time? BATC is designed to run without other traffic. Could that affect performance? I would also think you might have some weird results.

No no... BATC injects FSLTL models, that's all. But previously, when I tried to do it, things would be fine for about 5 minutes while setting things up at the gate, then would tank into 15 FPS. Disabling traffic remedied that, only for it to get worse at touchdown when arriving. Now? Smooth as butter. Nothing really changed. I basically changed ONE setting I didn't touch before - LOD. Then I changed it back and things are fine. I actually put volumetric clouds on Ultra too and it's still fine. I am pretty happy cause I was really disappointed when it was happening.

A big factor might be SU5. It's been hitting vram and performance much harder than any previous SUs.

I'm still surprised its that bad though.

I would start with HIGH presets and adjust some of the sliders a little from there. Definitely turn off Ray Traced Shadows thats a perf killer.

TLOD - I wouldn't go above 200 personally with that rig.

I thought that part of the target for SU5 was to reduce VRAM usage, not increase it??
