FSR4 is out. Some say it beats TAA and DLSS

Featured Replies

It is sort of a jumping the gun method to install it. You don't need a AMD gpu, any Nvidia card capable of DLSS should work.

If your card is Nvidia, you need to download Optiscaler latest version. You do not need fs4.dll because: (f you download the latest stable release of OptiScaler 0.9.1+, the developer has bundled the official AMD FFX 2.2 SDK (which contains FSR 4.1 models) natively into the code).

Gethub Optiscaler Repository

Download Optiscaler latest current version there and extract it. Again, there will not be a fs4.dll file in the package, but that is ok, it is built in.

Download Optiscaler_0.9.1-final.20260427._DSB.7z and extract it. Move all the folders and files into your main MSFS 2024 directory which has the flightsimulator2024.exe file

    Hi all. I have been using Optiscaler for a long time with my AMD card. It works great but make your life easier and use the new Optiscaler Client. https://youtu.be/QdsFxeR8PAg?si=RgIB2GHHS10Z7N9g

    yes, it does work on nvidia cards, and in VR. I'm using it wit an RTX3060 and hp reverb g2, and have noticed a slight frame rate increase.

  • Would be great if someone could do a step by step walk through using MSFS and optiscaler. I’ve tried but don’t see the option for 4.1. In addition we need instructions for after installing what to sel

People are swearing the glass screens look better in fsr4 than in TAA. I'll take their word for it. On my system fsr4 is very stable and very high performance compared to even DLSS anit alias.

edit: if everything is installed correctly, when you boot up msfs2024 and use Insert. Near the top of the Optiscaler tab you will see "FSR3.x/4". That means you are really getting FSR4 when you choose dlss or taa in msfs antialias box.

I have read that it looks better, but the performance goes a little down. So make sure you have enough headroom.

Going to try it too on my triple 4K setup ( 5090). Tried it before but it was not clear to me what to do with all the files.

Stable and beautiful here. I am no longer a DLSS antialias fan. I locked fps at 50 and it never budged lower than 48 including landing and taxing. The trees look nicer, too.

From the OptiScaler site :

Supports NVIDIA hardware by allowing DLSS or XeSS use, but FSR 4 functionality is limited to compatible AMD GPUs.

AMD 7 7700X, 32GB DDR5, RTX 5060ti 16GB, 2 x Samsung 1TB NVMe, 1 x 4TB sata SSD, Windows 11 Prof

Do I have to switch the settings in the sim to FSR aswell?

I've been using FSR3 & TAA with my nvidia card and it has been a smooth experience. I definetly want to try FSR4. Maybe it will be added as an option to the settings. It doubles the fps, making panning really smooth. Locked @30, but I get 60. Love FSR3!

MSFS

I use TAA at 4K on a 5080 locked at 30FPS and a little bit of reshade sharpening.

Is there any real benefit to getting this??

I'll wait until it shows up on DLSS Swapper.

So you move all folders ( like external, images,Optiscaler, github ) and 17 files into the Microsoft.Limitless_1.7.28.0_x64 folder ?

For me, whit Amd 9070XT, FS4 is like day and night compared whit The default FS3, no shimmering and equal in quality, if not better compared to TAA.
