I have a question, maybe stupid but here goes.  I'm about to drop some serious dollar on a 4090, I'm going to buy a 4k monitor.  If I get a 60Hz monitor does this mean my FPS will go no higher than 60FPS even with FG enabled?  If so assume I have to go 120, 144hz or higher?

You can't display frames any faster than the monitor's max refresh rate, so yes, a 60Hz monitor limits you to a max 60Hz frame rate.

I highly recommend a variable refresh rate monitor with hardware G-Sync.  To have a good shot at FG you'll want a monitor with a refresh rate north of 100 Hz.

Don't bank on FG working miracles, though...you may or may not be able to keep things stable with it on.  In MSFS with DX12 and FG I see 80-90fps (to a 120Hz G-sync monitor) right up to the point where it crashes, usually 30-45 minutes into a flight.  Others have reported the same issues.  Not that the 4090 is a waste, though...the beast can still manage a stable 50 fps with occasional drops to the 40s in DX11 with TAA on the same system.  On a G-Sync monitor that's still very smooth with good IQ.

Hey thanks Bob as I suspected then.  What I didn't realise is how expensive 4k monitors above 100hz actually are!  

1440P high refresh monitors are more affordable but then the 4090 might be overkill?  What do you think?

I was tempted to keep my mouth shut but every time this topic comes up I feel compelled to point out the alternative. I use a 3090 with a 55 inch Samsung 4KTV. I have my system tuned to run at 23hz with all the graphic setting in MSFS basically maxed out. In the TV's on screen menu there is a heading called "Expert Settings" and under that heading, "Auto Motion Plus" and under that "Judder Reduction" which I set to 10 and "LCD clear View" which I set to on. The result is a silky smooth 46fps on screen all the time. No 4090 required.🤪

I have an Alienware AW3420DW 34-inch 3440 x 1440 21:9 ultrawide G-Sync monitor on my MSFS system ([email protected] GHz, 4090FE).  My P3D system has a 30Hz 55" 4K TV.  The 1440p monitor does a nice job...in an ideal world I'd still rather have a big screen on the MSFS computer, but as you observe, a large-format 4K, G-Sync, high-refresh rate monitor is very expensive.  Maybe if I ever grow to love MSFS I might go that way...for now the 1440p monitor will suffice.

As far as overkill--I don't think so.  Monitoring remotely with HWInfo, I see prolonged periods with over 400W steady-state GPU power draw, total normalized power in the 80-85% range, and GPU temp in the 60-70 deg range on the 4090 with MSFS running--it's working pretty hard to kick out those 50fps in DX11.  The previous video card in that system was a 3090, and it could manage 30-35 fps into the same monitor with the same settings.

The 4090 is by FAR the best GPU I've ever had in a flight sim machine--enough so that I have two of them now.

I tried using Samsung's auto-motion and had a significant (unacceptable) amount of input lag.  That feature does post-processing of the frames, so what you're seeing on the screen is delayed by the TV's internal buffering and post-processing.  If you can get past that, I agree, it's another alternative.

Thanks for your reply but.........I've got the budget to go big bang and since my days of FSX/P3D/XPlane and now MSFS I've NEVER had a top of the range rig capable of Ultra settings.  I work bloody hard and this is my little treat.  So I'm not cutting any corners.  I've just ordered my new rig so look forward to it arriving!

Thomas, the monitor above IS NOT a G-Sync monitor!  It is FreeSync Premium (which is OK... but not G-Sync).  You say you want to go first class on this build, then you should insure that your very nice computer will be driving a true G-Sync monitor.  "G-Sync Compatible" is not G-Sync.

Yea I've been doing research on that, one of the reasons I haven't hit buy.  I don't really understand this whole freesync, gsync malarkey.  I understand freesync is AMD and G Sync is NVIDIA but what am I losing by going with a "GSYNC compatible" monitori compared to GSYNC?

A graphic processor built into the monitor, that can enable syncing down to 1 Hz if the FPS situation goes that bad.

ok in English?  🙂

What difference will it making in MSFS?

 

Blurbusters may have an explanation of what are G-Sync and FreeSync.

HOWEVER, tthe majority of FreeSync/G-Sync compatible monitors may sync image (and therefore, prevent stutters and tearing) down to 48 Hz. While 48 FPS may be too low for gamers, 48 FPS is a dream for simmers.

G-Sync can make that refresh synchronization (and therefore, can prevent some stutters and tearing) for any framerate between 1 and whatever the monitor is capable to, thanks to a dedicated hardware built inside the monitor (that's why so expensive). Since framerates in MSFS are usually low (I mean, the majority of us strive to get 30 FPS), those who can afford a true G-Sync monitor will go for it. Hope this makes it clearer.

Thanks for reply, issue I'm finding is the GSYNC 4k monitors are really expensive and outside my budget.  I've already shelled out nearly 4k for the PC!  So I'm looking for a GSYNC panel no more than £600.  Can you recommend?

Understood. But I don't know what to recommend... specially since you're going for a 4090 and you may use Frame Generation in MSFS!

The pixels on a 28" monitor at 4K resolution are so tiny that the bandwidth and GPU workload needed to support the higher res is largely wasted, anyway.  And text at that size/resolution is gonna be fine-print small. 

In a standard 16:9 aspect ratio monitor less than 32", 2560 x 1440 resolution is fine unless you intend to put your face right into it at something like 18" viewing distance.  I'd think there are G-Sync monitors at that size/resolution that would be within budget.  At that res, a 4090 might be a bit of overkill, though--the previous discussion was about 4K and 1440p ultrawide resolutions.  You could probably do fine with a 4080 at the lower resolution.

Can't help with specific recommendations for the UK--my AW3240DW was ~$800 USD around 18 months ago.
