Just upgraded to RTX 4080.My specs are Z490 MB, 64 GB Ram, 4TB SSD, I9-10900 3.7 GHZ. Getting very poor fps. I’ve attached some screen shots. I’ve already tried lowering the settings to medium and setting TLD & OLD both to 100, I only gain 5-6 fps. Attached is a screen shot of my settings and the default airbus at Buffalo. Any advice would be appreciated.

Be aware that if you enable ‘frame generation’, it will not affect the visible FPS counter in MSFS. It will still increase the effective frame rate.
Took screenshot at Buffalo since it isn’t a busy airport. But if I go to Newark, the FPS drops down to 35. I know FG doubles FPS with AI, but I still thought I should be getting more from the 4080.
All - Got almost the same setup, little newer I-9-13900 and 4090, but my performance is excellent. Tonight on flight two stutters, about 1/2 second one on taxi out and one on taxi into dest. And I am not worried about FPS, as longs as my monitor is pumping out 240hz, the sim will do what it will. More concerned about temps on CPU/GPU, but those in the 50C range, and everything at ultra. You I think (aint no expert) got something set weird, wrong would be the incorrect term, because no one to my knowledge has done a in-depth performance benchmark using various hardware combinations and Video cards.
Several folks who do x-plane stuff have done those, with a nice chart showing all the benchmarks you should achieve using various hardware. There are videos showing what “one user” has done, but having exactly his combination won’t fly because no two PC are exactly the same. A range of performance is the best we can hope for. I sure don’t worry about as long as it just works. After AAU2 it seems to me to be better, but, new bugs have been introduced as well.
Your CPU is what is holding you back - just look at the mainthread frame times compared to GPU frame times - over 3 times longer. In fact, there is no need to run DLSS in performance mode as your GPU is being way underworked. Try DLSS Quality or, for even better quality with likely negligible performance impact, TAA.

Make sure you enable the r bar through Nvidia inspector that should help to get less stutters and a better performance. NV and shader caches should be cleared frequently too.

Hello @EloquentLake87 ,
Welcome to the forums!

Normal performance for a 10900, I had a 10850K@5 GHz until 2 months ago and the framerates with airliners were similar. Upgraded to a 7800X3D and gained +60% fps in CPU limited scenarios!
Hi
I have a very similar system (Specs further down) to you and I guess what your seeing is about right.
The screenshot below I just took on the runway at buffalo and the FPS seems about the same as you are getting. I have spent quite a bit of time tweaking settings trying to make sure that the render window remains in the green at the top. The screen shot here was taken with the Fenix which I think is a little bit hungrier than the ASBO A320 ( I don’t have that one installed at moment) . Obviously the figures on the left are with frame regeneration on.
The biggest benefit I have found with my 4080 over the 3080 I had previously is the temperatures, the 4080 rarely goes near 60 degrees, where my 3080 would have been constantly up around 80 degrees.
Hopefully MSFS 2040 will bring improvements if they are going to make better use of multiple threads.

I don´t think problem is HW here. I have also similar figures with i9-12900ks + 3080Ti and they were quite similar as well when I had a 9900k + 3080Ti before. The CPU upgrade allowed more fluent camera panning for instance, as my previous CPU was too weak for my GPU. I maybe got +5 fps in very particular scenarios only just by the CPU upgrade but that´s all. While being on ground or near dense urban areas the limitation in game it´s game´s main thread itself, not our HW. Basically it drives almost everything and that´s a design limitation. We won´t see significant improvements unless we had x2 speed CPUs or things like that because currently MSFS is still based on the brute force approach to handle main thread and that thread is the bottleneck, not the rendering.
The only effective way to evercome that situation I have found is to reduce overall viewdistance (TLOD). The other settings are basically not relevant. In my case even if that´s a 384bit card vs the 256bit 4080 the specs are still similar while the 4080 is logically faster, so the second limitation would be the textures size/quality. I decided to stay with the High setting instead of Ultra to avoid overpassing the 12GB memory limit as that setting had a severe impact while on dense scenarios or clouds and turned to use almost 100% or VRAM which also results in performance degradation during memory swap. Those would be the relevant settings to tune I would say as I didn´t find significant improvements by tweaking others at least, so 4080 would even behave better due to that additional 4GB memory by following a similar approach.
Remember that anything above TLOD 100 starts to kill performance. Going above TLOD 200 is a no go for me (FPS drop below 40fps and I start to clearly notice it, so for me that´s my limit) and even under DX12 I´m still below 10GB memory usage, so perfect for my overall performance.
Cheers

Thanks for the info. I lowered TLOD to 100 and decreased texture size and set textures to high. Picked up 7 fps. Will try some more tweaking, but until MS fixes problem I guess this is about as far as I can go.

There´s no need to go as low as TLOD 100, specially for that card. I have it at 200 and that´s still good to stay a bit above 45 fps, even on ground at complex airports. Monitor your card memory usage because your 16GBs may not even require the switch to High textures. Ultra could still be an option for you but only if you don´t see noticeable performance drops while on heavy cloudy weather or your memory usage it´s not too close to 16GB. If you see significant performance decrease then you would need to stay with textures on High (or at least cloud textures on High while overall textures stay on Ultra).
By the way… Just in case check that you have set “Max Performance” in the power management setting at NVIDIA control panel options. This allows clocks to work at their best. The power saving options will make them work below their default specs to save some energy and that can also reduce your card´s performance a bit.
Cheers
turn your object level of detail down to 50 . fps killer.
Agree with @geloxo you should be able to get away with at least 200 on TLOD, that’s where mine is set and in the picture I posted above I have FS traffic running and a overcast cloud layer. AI Traffic programs really do hit performance and I am still managing nearly 44 FPS in that scenario there with one of the more heavy resource hungry aircraft in the Fenix, in my experience.
On my 4080 I get 35 to 45 in intense areas and usually about 60 out in the country. Try TAA instead of DLSS I run at 4K 120HZ with V-Sync on and caped at 60.
Hi FreeBirdJosgh,
I guess you are the right person to ask a little question. Right now I am running a 3090 with 24 GB but the temperatures are very high. I am thinking about buying a 4080. I am also running a 42`` monitor on 4K with 120 Hz locked at 50%. Are the 16 GB enough when running on 4K with complex scenery and AI traffic and for example the Fenix bus, which is still missing update since nov 2022 a heavy frame eater…?!
greets Klaus
CptBayyer - First if upgrading to 4080 make sure power supply is big enough to handle the startup load that card needs. Yes, more than likely on the memory on the card, I’m running the 4090 and no issues. Mine has some water/rads cooling. I am in mid 50’s on temps on GPU/CPU. My concern would be PS and at least 32GB system ram.
4090 is king. You will need 1000w or biger to run it and 11gen or better processor. There is still no silver bullet you will always be chasing it. For the most part the 4080 is good if your on a budget but you will beneffit allot with the 4090 at abouvt 400 bucks diffrence. Josh
Hi Meridian, thanx for your answer. Power supply is no problm,cause it is a 1000W device. Should be enough :-p … But I am wondering, cause my 3090 is running with round about 82 degrees centigrade with peaks over 90 up to 95 … How do you have mid 50´s ?
Thanx Josh, can you say something about the memory of the 4080 running on 4K? Are the 16 gig´s enough?
