DDU Uninstaller has an option to clear nvidia cache.

Thanks for pointing that out, it seems thats the default setting now when you reinstall the nvidia app, was caught out myself really!

I've lost the link to the youtube video, but someone was trying out their new nvidia RTX 5090 over New York, and at one point they said that if they had the DLSS setting on 'Quality' it reduced the FPS by 30% or someat, and so they solved it by putting the setting to DLAA, and it freed up the bottleneck?! Don't know if that helps or not?

Also, in MSFS 2020 you could delete the rolling cache from within the sim to make it run better (supposedly), but fs2024 doesn't have the option to do that from within it, but you can still do it, by deleting a particular file. The file in question is named: "ROLLINGCACHE.CCC", and can be found in the folder: (Steam version) C:\Users\name\AppData\Roaming\Microsoft Flight Simulator 2024. Dunno where the Microsoft Store version is? The file will remake itself when fs2024 is restarted. So, thats something else you can do I suppose, that will help make the sim run more smoothly.💁‍♂️

Came across this stuttering fix on a youtube shorts, and after half an hour of flying the Cessna Skywagon (nice plane) South West from Washington DC, at 2000ft the micro stutters everyone complains about in fs2024 - they seem to have gone now. You have to do this: How to Disable HPET (Windows): [High Precision Event Timer] Open Command Prompt as Administrator. Run: "bcdedit /set useplatformclock false". (without quotation marks) Run: "bcdedit /deletevalue useplatformclock" (optional, to restore the function back to default). Restart your computer. "High Precision Event Timer (HPET) is a hardware timer used in modern PCs to synchronize multimedia, graphics, and system tasks, often replacing older timers." Have a Nvidia 4080 FE, AMD 5800x3D CPU, did use DDU uninstaller to uninstall nividia App & driver a day before, when I re-installed app and driver, made sure the driver had clean settings before install. Did also update my ASUS TUF 550 motherboard BIOS a day beforehand. Tried this with all sorts of graphics settings in fs2024's own settings, and its still smooth with each one - each time. With DLSS on, Quality setting, DLSS off, TAA, High or Ultra graphics settings, with or without the external program 'Auto FPS' running (with Auto Method within Expert Options set to 'FPS Sensitivity') You can usually see the micro stutters more when looking at the lower part of the screen, but it seems ok now? Give it a try, see how you go on, can always put the HPET setting back to what it was before, as I have shown above. This HPET function can also be changed with editing a registration value, which is essentially what you are doing when running this command in the command prompt. 😊

Oh....no, I have found the link, here it is:

No, don't have the link to the video, but the content of the video had someone explaining how you had to modify your registry, but I read down in the comments of the youtube video that you could obtain the same effect by changing the nvidia settings within the Nvidia Control Panel, so didn't bother with watching the video, just tried the settings, and thought that was just great! Feel its made so much of a difference. BBC 'Escape to the Country' episodes look like 3D now! Ha Ha.

To make your graphics look incredibly much sharper, so a 1080 video will look like 4K, try this: (if you have a nvidia graphics card) 1.Call up your Nvidia Control Panel by right clicking on the Desktop. 2. Go to 'Adjust desktop size and position' at the left hand side. 3. Enable 'Integer scaling' within the scaling tab. (most people have 'Aspect ratio' enabled) 4. Go to 'Manage 3D settings' at left hand side. 5. You should notice a new option at the top of the list named "Image Sharpening", click on it and a small window should appear. 6. Set 'Sharpen' to: 0.65, and 'ignore film grain': 0.17. Thats it! I found after doing this, (which was derived from comments in a youtube video) everything is so much sharper (have a nvidia 4080 graphics card) the sharpness of aircraft and everything else within Flight Simulator 2024 is very pleasing to behold! Also, videos are so nice now. Good luck with it.😀
