Just install my RTX 4090 but very poor FPS - Looking for support

My recommendation, turn OFF Hags, turn off Vsync, turn off DLSS frame generation, enable Nvidia Reflex Low Latency = On + Boost, and keep your Ultra settings. Ultra settings will ensure you stay GPU bound, which is required for Reflex to work properly. Let us know how that goes.

Thanks for feedback. I just followed your steps leaving in Ultra and i gain 3 to 5 Frames.

is still very weird, if i set my settings to medium instead of ultra i get around 38 FPS, i would expect at least to jump over 48!

@geloxo

click anywhere on main game screen so that game rendering gets priority

how do i do this?

[FelipeTurbay]

@BegottenPoet228

ight click the .exe again go to Set CPU Priority and select High

thanks just did this, will see if its works…

[FelipeTurbay]

@Fornax4188

Whsts your TLoD setting. Thats very heavy for the CPU if you have it at 200+. Try 100 and gradually increase and see what the CPU can manage

Thanks, just tried this, but it does not make any difference. The FPS are some how struck in between 30 - 35. I can changed a lot of settings but i am not seeing any gain in FPS…

Just move mouse around cockipt and left click on the windshield for instance. That´s enough to force MSFS to get rendering priority. If you see your windows standard icon for the mouse pointer (which never vanishes) then game is not getting priority but windows desktop is getting it instead. If you see game´s own mouse pointer icon (which typically vanishes after some seconds) then game is getting priority.

Unfortunatelly you need to repeat that process everytime you switch from game window to any other app window, for instance if you operate anything on a third party moving map app which is displayed on a second monitor or even if you have pdf charts open on a window while still using just one monitor. That´s disturbing but it´s how game and Windows implementation is. Anything on the foreground still needs to be clicked or Windows desktop will get rendering priority instead of game.

Cheers

What is for me still very annoying is that I have exactly the same system setup (except for a different mainboard) as Marc from the sim hanger

In this Video he doubles the FPS by using the DLSS in 4K

140 FPS in Microsoft Flight Simulator | RTX 4090 & DLSS 3 tested in 4K, including PMDG 737-700

And if I set all the settings are he shows I only get around 35 FPS without seeing zero difference if DLSS is on or not…

This is very weird

Yeah, something is wrong with your CPU load. Your GPU seems to run fine.
For comparison, this is what I’m seeing with an i9 9900k (at 5.1 Ghz) and an RTX 2080, settings mostly in the HIGH to ULTRA range, Render Scale 100 and moderate LOD settings:

If even MEDIUM or LOW settings don’t give you ample performance, my only idea would be to check if your CPU is probably throttling down, which might be caused by cooling issues. A benchmark test and CPU-Z would be the tools I’d use. But first I’d try to bring back virtually all settings inside MSFS to LOW and work from there.

[RATTMAN]

The real fix is cpu multi threading. I have a i9 13k and still bottleneck like crazy if im at an airport like jfk or lax. I only do TAA as DLSS3 isn’t clean enough for my taste. Mix DLSS3 and dx12 artifacts and it’s a meh show. Frame generation is only going to help if your frames are stable without constant freezing and fps drops.

[DrewmorKuZy]

Hopefully msfs 2024 will help cpu multithreading a lot.

[RATTMAN]

Me too. DCS multi threading update has helped that sim a lot. XP12 also needs the multi treading treatment. I’m sure it’s easier said than done though.

[OldpondGL]

Wow, you just can’t get the settings high enough to make the GPU work. How about increasing the Ultra settings? LOD 200 or max, Object LOD 400, Texture Supersampling 8x8, may even Render Scale up to 110 or 120?

[NixonRedgrave]

@OldpondGL

LOD 200 or max, Object LOD 400

Those will load the CPU, not the GPU.

[OldpondGL]

True. I’d like to see the results though.

@TomL7753

check if your CPU is probably throttling down, which might be caused by cooling issues.

This is interesting, I never get to see any green color in the FPS display even at low settings. You meant that probably the CPU is running too hot? Wouldn’t understand why since I didn’t changed the CPU cooler. It was fine before with my 2080ti…

[OldpondGL]

Set the resolution to 1080p, you’ll get green with high FPS. But you want to make 4k work, right?

[FelipeTurbay]

@OldpondGL

LOD 200 or max, Object LOD 400, Texture Supersampling 8x8, may even Render Scale up to 110 or 120?

I didn’t mess around with these settings and I end up seeing a reduction of FPS to around 25, so it impacted negatively

[OldpondGL]

So, it’s the CPU that can’t go fast enough. Try 1440p.

[FelipeTurbay]

Yeah 4 k! I had before an 2080ti and it would fine in middle settings. But I was expecting a boost with the 4090 which never came,? So far at least…

[OldpondGL]

How many watts is the power supply? Also, don’t get hung up on FPS. It is smooth? Does it look good? That last screenshot in the thread was at 2560x1080, so not 4k.

[OldpondGL]

Turn the Terrain LOD down to 50, just for testing. Then post a screenshot. Then set TLOD back to 150, but set Renderscale down to 75%, just for testing, and post a screenshot. Terrain LOD is the biggest CPU hog in the sim.
