September 12, 20223 yr Hello everyone, I am new. I begin by telling you my components: i9 9900k RTX 3080 32 GB RAM 1 TB SSD NVME2 850 watts PSU z390-f Game in 4k good components Now when I try to play msfs, I notice (with msi afterburner) that the pc performance is low. Low gpu usage and low fps. I've never had this problem with any other type of game, not even trying to play the newest and heaviest ones. Assuming that even when 1080p is very low, the fps are always the same. And that's why I can't understand what the problem is. The pc temperatures are normal and do not even touch the temp limit Please i need help i really enjoy playing that game but playing it in 10 fps totally ruins everything.

Also what is low fps for you ? https://fsprocedures.com Your home for all flight simulator related checklist.
September 12, 20223 yr Yeah that's very low with your rig, with a decent CPU and GPU. You should be able to set global settings to ultra, but beware of the terrain LOD. That's sort of the "fps slider" in MSFS. At major hubs like KLAX, EGLL with AI traffic, you probably want to reduce TLOD to 100-200, as otherwise your CPU will be hammered. Like the turtle above said, check in dev mod (in the menu), then on the dev mod menu on top of the screen, options=>show fps. This will bring up a display with your mainthread (CPU) and GPU frame times. Whichever is higher is the limiting factor. To reduce load on the CPU: lower terrain LOD, AI traffic, road traffic, boats etc, everything that moves To reduce load on the GPU: reduce resolution, render scaling, clouds ultra=>high Your 9900 has 8 cores, 16 threads. So if we're lucky to get a decent DX12 implementation with SU10 this week, CPU usage should be much better. EDIT: Oh, and welcome to Avsim!

September 12, 20223 yr Make sure you don't have a low power limit set for the GPU in Afterburner. I haven't used Afterburner in some time, but I had a similar problem a while back with another GPU utility (EVGA Precision) that turned out to be a really low power limit that somehow got set after I updated the nVidia drivers.

September 13, 20223 yr Author Hello and thanks to all of the replies. So I tried to do what you told me (AI Traffic LOW and road traffic ...; Low Terrain LOD set to 50; I also closed msi afterburner and activated the dev mod; I put the nvidia setting on "prefer max performance ") In short, I did everything. The problem still persists, with dev mod and with the fps setting active, the problem is as before, maybe 3-5 fps more (I'm about 20) Now I'll show you the fps with the dev mod guys I don't know why but it doesn't make me put the photo on the post. So I put a mediafire link on it. https://www.mediafire.com/view/cix44nw971ddefk/fps-problem.png/file
September 13, 20223 yr Hi Alex, Strange problem, but you're not alone. Never heard of "limited by rdr thread", so I tried to find out and did a Google search. Looks like there's something wrong in NCP, just Google it yourself. Good luck Mick PC: Gigabyte X670 Aorus Elite, AMD Ryzen 9 9900X3D, Gigabyte GeForce RTX 4080 Super Aorus Master, DDR5 G.Skill Trident Z5 Neo 2X32 GB, Corsair HX 1000, Fractal Torrent, Samsung LC32 / G7 1440P.

I'll just post it here (I'm using imgur by the way) so that others can see. But what I can see from the dev mode stats is that you're limited not by mainthread (CPU) or GPU, but RdrThread. FPS: 20.7 MainThread: 22.5ms RdrThread: 48.0ms GPU: 25.7ms I'm not familiar with RdrThread myself. Here's a thread on the official forum https://forums.flightsimulator.com/t/low-fps-limited-by-rdrthread/370489, maybe that can be a starting point. And perhaps others will chime in. 7950X3D | RTX 4090 | 64GB DDR5
September 13, 20223 yr So a very quick search seems to talk about RdR (Render Thread) problems not being new in MSFS. They may have first been noted after SU5 when TAA was introduced in graphics settings. There may not be a one single silver bullet here, but solutions suggested include ensuring you do have TAA set in your graphics options, and that the CPU ‘priority’ level for flight simulator.exe has not been set to below normal for example. Hope you sort it, with a spec like yours it should be blazing fast! Good luck

September 13, 20223 yr Maybe you can also read through this: https://forums.flightsimulator.com/t/low-fps-limited-by-rdrthread/370489/9 Strange problem though.

I have been suffering 2fps and limited by rdrthread a few weeks after SU6 as well. I have tried many hours of troubleshooting the problem, updating/reinstalling the graphics driver, tweaking MSFS graphics settings, removing files from my community folder, multiple re-installations of MSFS2020, upgraded to Windows 11 all to no avail! I uninstall citrix and boom! Problem solved!!! Edited September 13, 20223 yr by MySound
September 13, 20223 yr Author Hello again I tried to take a flight. Throughout the flight, the fps graph looked like this. And the rdr thread was always normal. I haven't changed any settings since my previous post. What do you think is the problem? However, having read many forums regarding these problems I noticed that many people have formatted the pc, I would not want to do it as I have many files, but if the only option is that I would also do it ... Anyway, I want to thank you for the help you are giving me! Many thanks
