I said it once and here again:

only cause windows shows that VRAM is „used“ doesn’t mean the game needs it. It’s allocated memory which is different from used memory. 
 

If you know Java - it’s quite simple. The application allocates memory. Every now and then runs the garbage collector and frees up the memory. 
 

if you have 24 instead of 12 gb - the garbage collector says: not today!

And the crappy P3D engine is not the standard anyways. 

Exactly. Sold my 3090, got a 3080Ti for 800 Euros less and performance is pretty much the same, even though MSFS was also allocating (not effectively using) more than 12Gb of VRAM sometimes.

How do we exactly see how much is being used? I’m guessing task manager isn’t good for that? I look at EVGA X1 Precision and it shows the same as task manager (9.5GB “used” out of 10GB)

TBH for GPU / VRAM I don't know.

For RAM you can see it in the Process Explorer.

I don't use MSFS yet ( i am on P3d 5.3 HF3) and the performance boost is AWESOME 🙂

With a i9 1100K running at 5.1 GHZ a 1080ti would struggle to hold 30FPS at some addon airports.

Now with a 3080TI , i am holding 40FPS or higher with high AA, AI traffic and the FSL A320.

It is also DX12 and more GPU resources are being used . 

I've just installed my new Evga 3080ti Ftw3 Ultra at a cost of £1300 for use in MSFS and I must say I did hope for a substantial increase in frame rates. On the same settings as before its bouncing around 35. I upgraded from a 1080ti. Developer mode is saying main thread limited which again surprises me as my i9 9900k is clocked on all cores at 5.15ghz. Sure I can now push tender scale from 75 to 100 and clouds on ultra amongst most other things on ultra as before though level of detail beyond 200 is bringing my system to its knees. Guess I'd need to throw another £1200 at it for a new MB, cpu and memory but that will have to wait.  Just concerned given the current speed of my cpu that any upgrade will see the same results.  Running the sim at 4K also.  Have yet to run Traffic Controller to inject AIG traffic but the above just when using live traffic (which is less intensive)

Yup, I have same cpu but with a 3090 (so basically a 3080ti with extra vram) and also run 4K. Can’t get TLOD above 150 with out becoming main thread limited and inducing stutters. Try setting your TLOD to 150, and your instrument refresh rate to medium. That should free you some cpu cycles and make you GPU limited. All other settings you can basically max with that graphics card. 
Also, any traffic also affects the cpu and not the gpu. I don’t believe there is much point in upgrading the cpu yet, see what happens with DX12, and what new cpu comes out later this year. 

Hey Guys,

Some great info here. For once in a blue moon the tax man was nice enough to give me a refund this year!! I have been sitting on the upgrade fence for a while but this time I really am struggling with which road to take.

I have an i5-9600K clocked at 5Ghz, a 1080TI & 32GB DDR4 3000. I run MSFS locked @ 30fps in full 4K on a 43 inch TCL TV. I generally find my CPU usage sits around 60% and I try and keep my GPU below 90%. I run mostly high settings with a few Ultra and TLOD at 150 and OLOD at 200. At really busy airports I drop the TLOD to 100 and OLOD to 150

My CPU choice is the i5-12600K (Of course with new MB & RAM) or a 12GB 3080. I only want to do one right now but this upgrade decision is way harder than any others I have faced lol I know my 1080TI is the bottleneck at the moment so would it be better to upgrade to a 12GB 3080 first?

I am not expecting miracles as I intend to stay locked at 30fps with my TV @ 30Mhz

Please help me out lol

Thanks in advance

I know I said I was going to wait, but I didn't.  As some of you know, as Sylvester the Cat once said in "Birds Anonymous" -- "I'm weak!!".  I can't resist playing around with hardware.  The 3080ti price drops were enough to get me to do it...that 1080ti in my sig won't be there much longer.  I was also tired of my 1080ti being barely adequate for 4K.  Adequate, but only just...

Now I won't have the problem.

So Richard to your question, you can see what I did.  I decided to run the 3080ti first.  I'll take care of motherboard and cpu later.  My power supply is an EVGA 850W 80+ Platinum.   The card I bought is an EVGA card also.  EVGA sells two versions of the 3080ti, one is their "FTW" version which has a higher base clock, but the card is a little longer.  I ended up buying the "other" EVGA 3080ti which has a slightly lower boost clock but is a shorter card that will actually fit in my case.  I figure the 2 fps I lose off the FTW version is miniscule for flight simulation purposes, as I may lock at 30, 40, or 60 fps depending on what my testing determines I should run with MSFS.

@Mace if you use Afterburner it doesn’t matter how high the clock is by factory default 🙂

I run an EVGA 3080ti FTW Ultra, converted to Hybrid - and afterburner is a MUST. 
My card is running in daily use at 1850 MHz and 0.82V to keep the temps and noise down.

I have found a brand new Gigabyte 3080 12GB Gaming OC for $1,354.87 CDN with taxes all in. I have seen a few 3080TI's used for anywhere between $1,400 - $1,700 the only thing I have been reading is whether or not the performance difference will be that much between a 3080 & 3080TI

I will be interested to hear how you make out, on paper there isn't a great deal between our CPU's for memory & single core performance

Ah yes....I forgot this...thank you.   I use Afterburner with my 1080ti...

My 1080ti is one of the EVGA Hybrid models, with a fan and a waterblock.

The EVGA 3080ti card I'm getting is all-air.  I may experiment with its voltages if I run into any heat issues.

This might sound a bit crazy, but I've just taken delivery of a 3090 Ti (ASUS TUF-RTX3090TI-O24G-GAMING) to upgrade from my Titan RTX. This is for a box with a Ryzen 3950x, running a big (55") 4k monitor. I got the Titan when it was pretty much new out and it made a massive difference to P3D (v4 at the time) and XP11. And in both sims I was frequently using well over the 11Gb non-Titan vram max. I could guarantee hitting 20-23gb usage around LA in XP11 pretty much every time.

The Titan has been pretty good in MSFS, but I still struggle to get a consisitent 30 fps (my target) in some areas. And yeah, yeah, I know I could just reduce my settings to smooth things out but when the sim first came along I was quite happily running everything at ultra and with my LODs set at 500. Gradually, since maybe SU5 the sim has been getting harder (no, actually impossible) to run at anything near those settings/LODs and although I did drop my LODs to 350 and a lot of my visual settings to high, it still doesn't feel as smooth as it should. I see plenty of 4k videos that are running at much higher frame rates and a lot smoother than I get, and I see plenty of images of perf monitors from some of these newer cards that just got too enticing.

The bottleneck calculator was telling me my CPU was being throttled by the Titan (by something like around 20%), but indicates that the 3950X and 3090ti are a perfect match, so we'll see. I did consider a new machine altogether but there didn't seem that much improvement to be had in terms of CPU, and I don't have the patience to wait for whatever is going to possibly come along later this year. And anyway, the new graphics cards are almost certainly going to fit better in whatever new CP/mobo architectures are presumably also coming along, and then it really starts to mount up. The rest of my system is pretty solid (MSFS is on a 4Tb 6gb/sec PCI/NVMe card and everything else on ordinary SSD), so if this don't fix it I don't know what will.

I eBayed a whole bunch of unwanted vinyl albums a few months back, so this is my little treat to replace those (and that was a whole other experience and eye-opener as well). I plan to get it installed over the weekend and I'll post my feelings about it all after that, in case anyone is interested.

You should definetely undervolt it. I am running my 3080Ti @ 250W @ 95-100% Core Load (around 100W less than factory settings) with very little performance impact. Great for the card, for the environment and for my wallet...

And the best thing is you virtually loose no performance 🙂

Everyone talks about undervolting, but after overclocking my CPU and the learning curve that came with it, I don’t really feel like learning this whole ordeal now… would like a bit cooler temps though.
