Hello, I'm considering the upgrade mentioned in the thread title, and I'm curious if anyone else here has done a similar upgrade and what your experience has been?  This is in MSFS.

The reality is that paired with my RTX4080 and the frame generation it provides, I'm pretty happy with my current performance except at large airports/large cities/lots of AI.  Placed like New York/JFK, Toronto, Philadelphia, London, LAX etc with payware airports, an airliner and AI bring the system to its knees...I'm often getting as low as 12-15fps without frame generation resulting in 24-30 fps with frame generation but generally I find frame generation to be pretty stuttery at those levels so it's not a good 30 fps if you know what I mean.

So I'd largely be upgrading to try and solve my big airport issues.  I'm wondering what kind of improvements I might see in these situations or is it just that the way MSFS is these situations are hard for any CPU to handle?

Money isn't really the object here, it's more my time/hassle of building the system, crossing my fingers it all works, and likely having to reinstall windows etc which gives me anxiety just thinking about!

Thanks for any input. 

I don't have direct experience but looking like about a 40-50% increase in CPU performance which is pretty significant.

I did this upgrade almost exactly, except I went with the 7950x3d.  Expect a pretty large jump in performance, worth it if you have the budget for it.  In my case it went from stuttery in cities with LOD 100, to being buttery smooth at LOD 200 even with addon scenery and the pmdg 737 in NYC.

Thanks, I appreciate the feedback although now I feel like I have to do the upgrade haha.

What did you do in terms of windows, full reinstall, repair or nothing at all?  That’s the part I really don’t want to deal with…reinstalling my games/steam library and dealing with all the saved games, mods etc that I have installed.

When I upgraded from an i7 7700k to my current 10900k I did nothing with windows and it worked fine, I’m thinking this may be a bigger issue going from I two to AMD?

From Intel to Intel, plug and play no stress.

From Intel to AMD, I would do a clean install. I did a similar upgrade earlier this year and found that doing a clean wipe was the smart move.

Are you sure your CPU is the problem?  I run MSFS on a 10900K @ 5 GHz and a 4090FE.  I just did a flight out of JFK (iniBuilds, a known heavy fps hitter) in the A310 with lots of AI traffic (FSTraffic) and with FG on, I didn't see frames drop below 55 fps.  VRAM usage was a surprising 23GB, though.  I wonder if VRAM paging on your 4080 could be part of the issue (?).

Generally @regis9 there isn't a panacea solution, in that you can indeed overload the hardware if you get happy with AI settings and TLOD.

I would definitely start fresh with the OS install.  I don't want to sound like the movie Aliens but, it's the only way to be sure.

That’s a really interesting question, what’s the best way to monitor VRAM?  Definitely worth a look before I jump to a new cpu.

I use HWInfo64 (freeware).  You can also run it in host-server config to monitor your sim machine on a separate computer (e.g. a laptop), which is how I do it.

 

Thanks Bob I’ll check that out.

Ok, so this is interesting, with TLOD at 100 (my normal airliner/big city setting) at inibuilds KJFK I bottomed out at 251mb of available VRAM.  Going even further down to 50 TLOD I was around 400 MB of VRAM.  I'm not sure if numbers that low are indicative of the card basically running out of VRAM or if a buffer of VRAM is kept rather than actually hitting 0?

So this is very interesting.  To be honest I had been contemplating an upgrade to a 4090 anyway (selling my 4080) so now I'm left wondering if that might get my performance to where I'd be happy in the specific scenarios where it's currently dragging?

ini JFK is a frame rate hog (and vram hog).  Period.  It's the toughest scenery I've ever run.  I'm only running 1440p but if I run tons of FSLTL ai traffic and an advanced avionics aircraft like the Longitude enhanced or even the FSW C414 with dual TDS GTNxi's my frames really suffer.  Add in heavy weather and (oops my bad) running TLOD around 400 (lol) I'm in the teens w/o frame gen as well.  I'd say the CPU is definitely a factor when you run high end scenery, aircraft, ai, and heavy weather in dense photogrammetry areas.  I've got the 12700K and am still occasionally CPU bound in those heavy scenarios.  So yes, I think that new AMD would help you.

My machine is getting updated with 7800x3d, 7900xt gpu, new higher end mb, 32 ram and 2 additional m.2. It’ll be my first amd build in years. I’ll get it back next week. Previous hardware was an i9-9900k, 2080-8 gig etc which I got five years out of and hope to get another five years from this one. Not inexpensive initially till you look at it by the hours of entertainment. Less expensive compared to putting 2 or 3 boxes through my 686 every month.

I would go RTX 4090 with that if you can afford it...  I realize it's a pricey card though.

Hi Ryan,

Thanks for the thoughts on the 4090 but I've already bought the 7900xt (20gig)

Just purchased and getting installed the 7800x3d, mb x670e-plus , 32 gigs 6000 ram, P240 cooler and a couple more m.2 drives. There will be a total of 9tb of m.2 drives space and 4tb on two ssd drives. Should be reasonably future proofed.

It'll be interesting to see how all this works but I suspect it will be pretty good.

About every 5 years or so it seem i do a large upgrade. I have found buying the most horsepower you can fit in the budget is less expensive in the long run from the years it'll do most anything I want.
