hi ianrivaldosmith

i have G Sync compatible monitor 240hz  4k

3080 graphics card

7800x3d cpu

trying to figure out settings for this monitor could you help at all please

just trying lossless with your settings but dont know how to setup with 240hz monitor

Hi.

The higher the hz, generally the higher base frame rate you need or frame gen x3 or 4. If you want to get close to the 240hz that is. 

What is the minimum stable frame rate you can achieve? And is your monitor G-sync? 

@Ianrivaldosmith, sorry to ask you another question. Currently I have 29 set as max fps in Nvidia. The lowest it will accept is 20 which is what I was previously using with X3. But that had no buffer so there were stutters.

But RTSS has no minimum. I’m going to try 19 in RTSS tomorrow with X3. That will give me a buffer of 3fps.

The upside is I can increase settings especially Ai. There may be a downside. Thoughts? Worth trying? More artefacts?

My monitor has no GSync and is set to 60Hz.

Generally speaking the lower the frames, the more artefacts you will suffer. That’s why it’s actually recommended to have 40 as a good base, down to 30 occasionally. Anything below that and you will get artefacts, it all just depends on how much they annoy you. Some people barely notice them, others can’t stand them. 
 

Oh and increased input lag with X3. Again, some don’t notice, others do.

Hi @Ianrivaldosmith good to have you and your knowledge back!  I remember when you were right on the bleeding edge of G-Sync and FG when they were introduced.  Good to have you back.

Thanks. Even with a very good system 40 is a pipe dream at Heathrow with Concorde and lots of Ai. 30 is just about attainable with reduced Ai and scenery settings.

I’ll give it a go just as an experiment and report back.

hi ianrivaldosmith

thanks for quick reply

monitor is g-sync compatible

i usually cap fps to 40 in rtss

use frame gen mod do you turn fg mod off if you use lossless

So if you cap at 40 and want to get close to 240hz you’d need frame gen at X6, which is a lot! 
 

I would try capping at 50, and running X3 and see how you get on? Make sure you follow my guide RE G-sync, and V-sync etc..

 

Also I’ve never used frame gen mod, but it sounds like it’s doing a similar thing, so, don’t use both at once. 

thank you

i will try that fg mod off

i will read your guide again thanks for your time

What hz is your monitor? did you lock your frames? Do you have G-Sync? there are lots of variables to take into consideration. You can't just X4 on 30FPS and expect miracles. There are far better ways to use the program than that. See my guide

120 Hz, can be set at 144 Hz too.
Yes: 30 FPS using RTSS (Front Edge Sync, a.k.a. Noel's method). I can keep 1% lows at 29.9 FPS with my MSFS settings, except in some scenarios. 
G-sync compatible, but I never liked the results in my rig. Supposedly, it can sync down to 23 Hz. My fixed 60 Hz laptop display feels smoother.

And actually, 30 FPS +4x FG in a fixed 120 Hz monitor is my sweet spot for airliners (such as Fenix/iniBuilds). I don't like when I go to a lower native FPS and then I set a higher FG factor to compensate; it doesn't feel the same. BUT I never tried leaving some headroom for FPS (i.e., setting a total of 116-117 FPS for a 120 Hz monitor). I'll try your guide (with both 29 FPS+4x FG and 23 FPS+5x FG) and edit this post with my results.

EDIT: got some replies to this post. I'll instead reply too, instead of editing.

Just a heads up; Enhanced Sync, Fast Sync & Adaptive Sync do not work with lossless scaling.

Also, try turning your g-sync on with your frames not exceeding 117fps. 
 

Also, another tip:- Add LosslessScaling.exe to NVIDIA control panel / app then change "Vulkan/OpenGL present method" to "Prefer layer on DXGI Swapchain"

 

Ohh and for those who still have two graphics cards (like back in the day), it’s possible to generate the extra frames on another GPU, removing the load from your main GPU 😉 I believe this can work with iGPU too but I’ve heard mixed results and personally haven’t tried it.

Never hit your refresh rate, you’ll introduce juddering. Always keep it 2-3 FPS or more below. This allows for some frame spikes and still keeps it below your refresh rate. 
So, do 29X4.

Ray I'm using Lossless ver. 2.3 and 3.0, 2.3 only when I start to notice flickering that I only get on 3.0 I lock at 19 fps with RTSS and use 4X in Lossless and it's fantastic - a few artifacts here and there but the fluid fps and virtually strait line response time more than make up for it. I don't know if you'll have a different experience in P3D, but assuming it is similar to what I see in 2020 I think you'll be pleasantly surprised.

The only other comment I would make is that I don't know whether you will experience stutters running 57 fps at 60 Hz monitor refresh. Maybe Vsync can play a role, but I don't know.

What’s your monitor refresh rate?

Ian said VSync must be off to prevent problems. Off in the sim and off in the LS app.

Because fps are restricted to a max of 57 on a 60Hz monitor and crucially with VSync off there is a 3fps buffer. That’s the crucial difference to when I had 20 set with X3. No buffer there.

I did 23x5 (which also falls short of 120 Hz) and with Vsync disabled everywhere, it helps a lot regarding input. Thank you very much.
