Anyone with a 4090 and using 1080p?

Considering upgrading to a 4090…

I currently have a 5800X3D, 3080 10GB, 32GB RAM etc but due to space and my setup (I share my flightsim monitors with my work monitors) I can only game in 1080p…

The main reason for the upgrade is that I’m sick of the frame drops when using VATSIM and model matching, especially when landing and taxi in. It ruins the experience for me. Heard good things about frame generation so wondering if in my situation it would cure this even if the 4090 is massively overkill. I can up the render scaling to 200 haha

That’s a huge waste for a 4090…if you can afford a 4k monitor youll get your money worth if not the 4070 will be perfect…IMO

Pointless upgrade at 1080p. Usually 1080p forces a CPU bottleneck, so performance will be controlled by the 5800X3D. You will likely see no performance benefit going from a 3080 to a 4090 in this scenario, with the exception to frame generation.

I would use the money to purchase 4K monitors, as your current 3080 can handle 4K just fine.

Try a modest TLOD setting first, like 100 that I use with my 5800X3D for a very smooth flying experience, including landing and taxiing.

I don’t honestly see the point in buying a $1500+ GPU to use it at 10% capacity at 1080p. Particularly if you already have a 3080. A 4090 can easily drive a 4K display at all maxed out visual setting with tons of headroom to spare. It would be better suited to a 4K multi-monitor cockpit setup.

I would be surprised if a 3080 is even 50% used at best of times at 1080p. The CPU is the bottleneck in MSFS, not the GPU. An upgrade to a 4090 (without frame generation) would show you the exact same performance. Sure, frame generation can artificially double that number, but any stutters or pauses you may currently see in busy areas you’ll still see with a 4090, as those come from the CPU.

Agreed. I just switched my power mode from high performance to AMD Ryzen high performance and got a good kick in CPU performance. You should try it also. There is even an Ultimate performance power mode but you have to execute a special command to get it to show up.

For Windows 11 at least, you run the following command ‘powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61’ in a terminal window with administrative rights. Ultimate Performance will then show up under power options in control panel.

I want to acknowledge this is from @ResetXPDR. Not sure how I missed these 2 nuggets…

Strange, I don’t have this option on my system…

I’ll try that command to see…

EDIT> It unlocked Ultimate, but no mention of Ryzen in mine…

I wouldn’t bother getting a 4090 for 1080p, it’s a massive waste. I have two monitors myself (5120x1440p @ 240Hz and 2560x1440p @ 75Hz) and my 4090 is fine.

i am not gonna comment about 4090 being overkill for you as it is your money and you are free to do what you want.
Just make sure you have ~1000 watt PSU and buy proper cable that you can connect the card to the PSU directly.

Let’s say you bought it since money is not an issue and you are curious what you can do with it.
You can have triple screen setup. Or as you mentioned you can crank up everything to ultra and scaling to 200. You can buy a VR and try that. You don’t even need DLSS and can play high fps easily.

My personal opinion go buy it if you can afford it and upgrade to 2k screen or may be 4k later. if you are not that flexible on your budget listen to these people and don’t waste your money on it :smile:

Before using, I would read up on the ultimate performance power plan for AMD processors as one of the things it will do is disable core parking.

The plan I’m using is the AMD Ryzen High Performance plan as it has a less drastic effect on the processor than the ultimate plan (but still provides excellent results in MSFS).

Edit: the plan will show up after you update your AMD chipset drivers - see Youtube video:

Check out my mainthread in the picture below - smooth as can be with my 5900x locked at 40 fps!

Yeah, this matters a lot. I have a 1300 watt PSU personally.

I think this setting was abandoned in the previous chipset driver for some reason but has now been fixed (at least it shows in Windows 11) … visit AMD for the latest

I didn’t notice the AMD Ryzen High Performance plan until after I updated my chipset drivers to the latest version. It could have been hidden under “show more plans” though and I just didn’t see it.

As mentioned I used it for my old 3800X but when I upgraded to my 5800X and updated the chipset drivers it wasn’t available (not even hidden). The more recent driver has brought that back.

The Ryzen 3000 needed the specific Ryzen power plans, but the new Ryzen 5000 series uses the default Windoew power plans. From memory, this was because the new architecture introduced by Ryzen wasn’t compatible with the Windows power plan.

No idea why you’re seeing them again. Did they add new power plans for Ryzen 5000, or is it leftover from when you had the Ryzen 3000?

No, not residual. It came with the latest chipset driver and I am actually using it now without problems. Early signs once again suggest it out performs the Windows 11 offering.

I plumped for the 4080 in the end! Got the FE. Naughty me! I also set up my original 2k monitor to replace one of my 1080p monitors that i use for work. So much sharper! 4K musat be even better, I’ll be keeping my eye out! The 4080 is amazing though. Frame Gen is next level. I landed into EGLL with LOD set to 150, everything else at utlra, FSLTL traffic etc with about 50 fps and it was smooth as anything. Currently cruising over Norway at 115fps!

I own a Inno3D iChill RTX 4090 running a tripple 1080p Monitor Setup.
The only reason i still use them is, that 4k Monitors are much bigger… and i still want to keep my tripple monitor setup.
Replacing 3x 24’’ Displays with 3x 28’’ Displays requires about 25cm more width… And just replacing 1 of 3 is a no go … all 3 need to be exactly the same model … otherwise i could get in trouble with my (a german term) “inner monk”.

On 108ßp it is absolutly needed to set Render Scaling to 200 otherwise runway lighting during night becomes dark and ugly.

Bit like buying a Bugatti Chiron or Dodge Demon just to drop the kids off at a school.
