I'm still OFF with the sole objective to save VRAM and escape from the annoying popup warning windows. I'm using MSFS-AutoFPS. Didn't notice any fps or performance impact ON or OFF.

If you don't want to watch 8 min video:

Video strongly advocates for keeping ReBAR ON. If you are turning ReBAR off solely to save half a gigabyte of VRAM, your underlying graphics settings are simply set too high. Instead of disabling ReBAR, users should keep it enabled to fix terrain morphing and instead lower settings like Texture Resolution or TLOD (Terrain Level of Detail) to free up VRAM.

Well, this depends entirely on what is most important to the individual user. I am not lowering my settings just so that I can enable ReBar. I would rather save a small amount of VRAM on my 12GB RTX 4070 Super GPU, and keep the settings that I have now. Anyone with 24GB+ of VRAM will probably think differently.

Will try how it looks here with my 5090. I do have 3x 4K screens so I surely will see a difference

Well, never turned it off with my 4090, because VRAM is not an issue with my setup currently (single 4K monitor using DLSS Quality).

Off and I run out of video ram in a few places, but off, I get better performance most of the time. I could turn down some settings but it would be better if asobo could code the sim to reduce ram or dram usage when you are running low on either.

I do use the inbuilt dynamic FPS by the way (though could use autoFPS).

This guy and his videos ...

Please follow what works for your specific setup. Test with both on and off. Decide what are showstoppers for you and go from there. One guy and his experience does not translate into an automatic benefit for your own experience.

Over the years of testing both MSFS2020 and 2024 on my own rig there was no perf or visual difference that i could observe. With 2024 on my Rig the tangible difference is the freeing up of 600-800mb of VRAM on my memory limited card. For him to recommend for me to accept visual texture deterioration and lock up that 6 to 800mb of VRAM again for no performance benefit (On my rig) plus the additional cost of turning down my texture settings or lod is absurd. If turning it on is to fix popping then i guess popping has never been my showstopper. Low rez textures and bad LOD draw distance on the other hand make me not want to fly at all.

yes please test yourself, although island simpilot has sometimes good advice it's also a lot of clickbait / snakeoil ( yes I will get attacked), have a look at one of his latest live streams with the Pmdg 737, at Kmia plenty of stutters, and that's from someone giving setup advice.....Don't get me wrong I hope he continues with his chart explanations, but don't blindly follow anything what is told on Youtube or internet and by AI.

ive got a 5070ti with 16 gigs of vram and ofen get the out of vram message come up. I still think ms2024 is an unfinished piece of garbage that we are having to constatly tweak stuff instead of just being able to use it. Its like we are back in the fsx days with fibre factors etc etc.

it also still baffles me why the likes of HUES and other repainters dont do 4k as well as the super duper flashy 8k liveries the kids like.

we should just be able to use the sim without any of this rubbish in 2026.

Over at that other sim (we are not alllow to talk about) they dont have any of this silliness, Turn this on, turn that off, put this mod in to stop this window coming up, etc etc. Surely theres next to no addon scenery for it but theres none of this malarky

Completely disagree. While back in FSX days you werent able to avoid those things even with the currently best hardware due to its limitations (e.g. 32bit code), nowadays it seems more of an issue that people forgot that there is something called "settings" in the menue and that you have to put those settings according to the hardware you use. Nowadays, if not all settings can be put on "everything ultra max super duper", the game is "unfinished piece of garbage" (not only in the simming world, you can see that discussion for almost every game). Example: I have a 4090 with 24GB VRAM, yet I use "only" the setting "high" vor texture quality. Why? Because "high" is sufficient and it results in a nice overhead of free VRAM even in the heaviest scenarios (at around 20GB there). And personally, I do not see that much of a difference compared to "ultra", even on my 32" 4K monitor. Same goes for TLOD: I use AutoFPS to dynamically adjust the TLOD. No need for TLOD=400 when sitting on a huge airport at the gate. Also the built in dynamic setting does a good job in adjusting TLOD dynamically. But you have to use it... You have to adjust the settings to the hardware.

And you have to accept that even with a 5070Ti with 16GB VRAM, you are NOT running the sim on the current best hardware available, even if this statement hurts because of the sheer amount of dollar such a GPU costs...

Or in short: if you put those settings right and according to what your hardware is capable of (not: what you wish it should be capable of...), MSFS2024 runs perfectly smooth on almost every machine. If you have time and energy left for some tweaking, you can even make the sim run better (e.g. AutoFPS, dynamic setting). There is absolutely NO need to fiddle around with files comparable to the fibre factor stuff in FSX days.

Completely agree AnkH. However, for me, once you have run the sim with everything maxed out, it's very hard to go back when you install a demanding airport or other piece of scenery. I have to accept a few stutters as I can't unsee the eye candy I have seen 😀

Just checked and it was On. I will leave it this way as I have a 5090. Only when the VRam gets very low when using 3x 4K I will set it to Off.

Couldn't said it better than this.

Never touched Rebar myself and have left it on. I'm running a RTX4070 Super with 12Gb and so far did not experience any VRAM issues. Been flying MSFS for almost 1 year now with various aircraft addons and scenery.

I would be interested to know the various settings that you use, Mark......just for a comparison. I assume that you use MSFS 2024?
