Just upgraded from a 24" 1080 monitor to a 32" 1440 monitor.  Using an RTX3070 with a 5600X and 32 GB RAM, I was able to max everything out at 1080 but framerates well under half of what they were running at 1440, which I suppose stands to reason rendering twice as many pixels. No problems at altitude, but I'm getting 20 fps where I was getting 40 + fps on the runways.

It looks like I'm having to go from ultra settings to high settings, which seems to negate the benefits of a monitor upgrade and I've turned render scaling back from 120 to 100.

I've had to remove all of my addon photoscenery too in order to get and half decent performance.

I was always used to running a monitor at 60 hz, but the new one offers me much higher than that (120 hz and more).  Running at higher refresh rates does not seem to hurt performance and means I have no need to use V Sync, though I would like to understand a little more about this and how G sync works.

Any advice, tips or pointers (other than save up for an RTX3080 and a 5950X)?

Strange. The 3070 should be able to manage 1440p without issues. Usually on taxiways and runways the framerate is limited by the CPU (main thread), have you checked with the developer's tool if the GPU is actually the limiting factor?

G-Sync makes the monitor refresh rate synchronize with the framerate instantly, so if the framerate drops from 60 to 40 fps, at the same moment the refresh rate drops from 60 to 40 Hz. This prevents juddering and makes the gameplay smoother. For more info, Google GSync and you will find a lot of literature.

 

I would turn on dev mode to see what is limiting you. 
Then you can go on from there. I don’t think that 1080 to 1440 should drop the FPS by half. 
Make sure to use the absolute same scenario (especially weather) to compare the FPS. 
 

btw: a 5900x is faster in almost all situations than a 5950x. Especially in games

Yep, in dev mode, I was always CPU limited on my 1080 monitor and with the 1440 monitor, dev mode shows I'm being limited by the GPU.

I have a scenario I always use for testing which is the 172 at EGGD with few clouds at mid day, both with and without community addons.

Thanks for your simple explanation of G Sync McFuzzy, I found that quite helpful.

With options of 60hz, 120hz and I think 160hz, which should I be using?

I'm spending a lot of time tinkering and experimenting atm, but if I'm limited by the GPU, then I may have to seriously think about an RTX3080, but the prices are insane.  Thank heavens I didn't go 4k.

I have an 10850K and a 2080Ti. I just upgraded from a 1080 to a 34" 3340x1440 monitor. I notice no FPS reduction at all.

As a matter of fact, I think I'm getting better FPS since I lowered my render scaling in the sim from more than 100 back to 100. I think I had it at 120 or 130 with the old monitor.

...obviously, you could always throw more money at the problem.

Yeah, I was using 120/130 with the 1080 monitor and dialled back to 100 since I got the 1440 monitor.  It seems I'm getting decent frame rates at altitude but low 20s on runways and up to 1k feet and down in the teens taxi-ing around fairly basic airports.  Something not right here, but I can't work out exactly what.

Hnmm, this is definitley not right. I can testify this 100%. Some years ago I was running a 1080ti in FSX, and I had a test airport which was Orbx Anacortes. This was a particularly heavy addon at the time. I would get about 28fps sat at the end of the runway. I would use this scenario for all my testing. I went from a 24" 1080p to a 2K Apple monitor at 1440p. The frameerate went down to about 25, which effectively is about 10%, which when we are all talking about performance, is the yardstick (percentage) we should be referring to, not FPS. I hope this provides you with some helpful information.

Thanks guys, this is really worrying as I can't seem to find a solution other than turning down all settings and deleting all of my scenery addons, this defeating the object of a higher rez monitor.

MDFlyer - What CPU and GPU are you running?

If you have a GSync monitor, any refresh rate you set in Windows would work, because it will be just the maximum refresh allowed; the actual refresh rate when GSync is active, will always be the same as the framerate of your game.

If it's not GSync certified, a compromise should be found depending on the framerate you get most of the time. For example I used to have a 144 Hz monitor non GSync before, and I ran it at 144 Hz limiting the framerate at 48 fps (1/3 of the refresh rate).

If you limit the framerate at 30 fps, 60 Hz would work best. In other words, in case you don't have a GSync monitor, always make sure that the refresh rate is a multiple of your framerate.

Well I never.......Clutching at straws, I just turned on DX12 mode expecting worse performance, if I'm being honest and my framerates doubled back to where I was with the old 1080 monitor.  Can anyone explain that as I'm confused as hell.

I'm suspecting this might have something to do with the lack of VRAM in the RTX3070.

When I tried DX12 in 1080 rez, like most, I got worse performance and went straight back to DX11.

That's odd.  I went from 1080P to 1440 just a few months ago. I have a older i7 4790K with GTX 1080 Ti.

I was running LOD at 200 (out of 400) and at 1080P it was fine.  With the new monitor for real smoothness I have to decrease back to 100 LOD.  I don't see any significant FPS loss maybe except in photogrammetry areas (so I usually turn off PG).

+1 for Dev mode. I have a 3070 Ti, so not far off from yours, and have always played in 1440p with ultra 200 LOD. On the ground it is like 25-50 FPS but in the air at cruise its 55-75.

A simple mechanical video switch, of the non automatic kind, would allow switching from one monitor to the other with a push of a button. To make testing quick, and remove guesswork because  you are under identical conditions. Should cost about $8 or so on Amazon.

 

 

Render scaling of 120 on the 1080 monitor should be roughly equivalent to 100 on the 1440 monitor.

So dialing that back makes sense.
