What bit do folks not understand.

Your GPU should be at 100%.

If your CPU is at anything between 50%-80% then you're good to go.

Your Rig is realising the Game to the utmost.

Go Fly!

 

Seems like a lot of people are stuck in the past. This isn't P3D anymore.... Let the sim draw as many FPS as it can! 30hz and 30fps should be resigned to the flight simming annals of history.

Really?

With my 7 years old PC,just with upgraded GPU and RAM, Ím happy to have stable 30fps on 60Hz 65inch 4K TV anywhere I fly within the Sim. You will never resign 30fps, just think...and compare complexity and quality of Sims released years ago with MSFS, even powerful PC setup is fully utilized and future updates of SIM and new Addon will bring even more complexity...I don’t expect to play the SIM with fps more than 60fps with complex addons in future at all...and stutter free 30fps for civil SIM is just fine. Combat SIM like DCS is different “cup of tea...”...60+fps is required

Some interesting posts, thanks for all the replies fellas, appreciated. From my way of thinking, if a GPU is running at 100% then there would be some strain on it... clearly from what has been posted here, my perceptions are unfounded. I have to say though, as much as I love my 4K 43" monitor, it looks beautiful, I sometimes question my decision as I often fight for good performance. Most of the time in P3dV4.5 things are great, very rarely do I have an issue, but from my first tests with 2020, it is appearing that it struggles, and I wonder how it will pefrorm when PMDG release their NGX. 

I now a few people on these forums that have regretted buying 4k, the performance hit is huge, 3080 and the 3090 might be the start of 4k running OK, but I will stick to 1080x1920 and some AA.

I will PM you some time Howard, we never got group flights going in DCS but I am going to PM a few guys, are you up for some GA multiplayer mate?

If 30fps makes you happy, go for it. My point is don't limit the sim to 30fps, if you have a decent enough CPU+ GPU combo, then let it try and draw as many frames as possible!

Totally agree, this is not the 90s anymore, the only reason to limit frame rate is to eliminate screen tear - but if you have a freesync / G sync monitor and the hardware then just let it do it's thing.

No, sorry the idea of limited FPS is to give your CPU some head room when it needs to load a new scene or something else requires some CPU time, if you run at full FPS your giving your CPU zero head room, it's like running your car in the red line all the time. Limiteding you FPS gives your PC some head room when lets say you want to do a U turn, or load in a big airport. If your just keep running max FPS all that can happen is stutters and big FPS drops as you CPU ties to sort it all out. So sorry I disagree totally with the idea of running your CPU flat out all the time to max out your FPS 24/7.

GPU/VRAM is another story.

Also setting the resolution scaler to anything less than 100% means that you are not really running at 4K anymore.

Just a question, I assume you mean Render scaler ? If I put that down from 100% to 80% I see no difference, ie what I see is sharp, crisp and 4K goodness. I am also using HDR10 and Auto Motion Plus via my Samsung TV.

If I was not getting 4K, would there be degradation ? Just curious, learning as I go with this new sim.

Hi Dave, good to hear from you. Hmm, I have been absent on the forum for a while, I think spending a  lot of time on DCS, basically the past year, has diluted time I spent in P3D. I have to admit, my enthusiasm has waned somewhat too. I've been simming for 12 years now and I have been getting a little tired of things and my hope is that MSFS2020 will induce some new enthusiasm! Yeah, I spent about twelve months getting into DCS and most of that time was learning to fly the AV-8B properly. I did do a fair amount of online flying with a buddy and he created Red Squadron and he also had a private Facebook group and a bespoke squadron logo! I enjoyed the time I flew with the rest of the guys, about ten of us in total, it was pretty awesome. But I found the pressure to be somewhat overwhelming when flying with others who had nailed the flight systems and navigation etc and I had not put in the learning hours. If you fly in a squadron there isn't much room for being word not allowed of correct procedures. I enjoy flying when it suits me and not always when I feel I have to. Certainly GA flying would be fun. Sure, give me a shout.

That has always been my undertsanding of limiting frames too Dave. By limiting frames you're giving extra horsepower for scenery loading and not the GPU chasing framerates.

Not really. If you are gpu limited (which, Ideally, you should be), then the cpu has all ready done all of its work and it’s up to the gpu now...... So, limiting the frame isn’t really achieving anything, other than lowering Your frame rate. Just let the game do what it needs to do....... 

 

oh and if you want your cpu doing less work. That’s what the MSFS settings are for. Bring back your LOD for example, releasing the cpu of some burden, and then your GPU can finish off the work...... you want to aim to be gpu limited.

If you reduce the slider to 80% it means that your true rendering resolution is 3072x1728, which is then upscaled to 3840x2160. If you cannot see a difference then no harm in keeping it that way.

Why would anyone want to lower their GPU processing from 100% to 50%?

You are missing the point, its not that we want to lower the processing power, its about making the sim more fluid at 30fps if a steady 60fps can't be reached, the reduction in processing power is just the result of it and besides, having some processing power headroom means I can crank-up a few more eye-candy settings.

No, you are missing the point. The point being the post was talking about the GPU being at 100% (which it should really be), and you are talking about the CPU......and if you are CPU bound, then lower some MSFS settings until you become GPU bound. It's not exactly hard. 

I can understand if one decides to cap framerate to keep the rate constant.

But nobody has to cap the framerate to not utilize 100% of the GPU. If that would really be a goal, a lower level graphics card would be the much better option.

100% agree! This is the exact reason where it is favourable to lock fps.

My computer is old now. My GPU is running at 100% and framerate is jumping between 35-50 unlocked. When the framerate is fluctuating like this your frames will be delivered from your GPU to your monitor at different times.

With a framerate of 35 every frame will be shown at 28.57 (1000/35) milliseconds. With a framerate of 50 every frame will be shown at 20 (1000/50) milliseconds. These differences in delivery from your gpu to your monitor will be seen as ”judder” or stuttering. It only happens when the framerate variates which it usually does alot when uncapped.

At high fps, like over 60, its not much of an issue as the time between frames are very low. At 35-50 fps it can really ruin your overall experience as the time between frames are longer.

A too low overall framerate, even if locked, imo 20-29 fps (50 - 34 milliseconds/frame) is quite stuttery even if delivered at a steady rate just because 50 milliseconds is actually quite slow to the human eye.

Just saying ”max out your framerate, let your gpu run 100%” I think is not the best advice because there are so many factors behind getting a fluid experience.

I don’t limit framerate because I want to. I limit it because I can get a steady framerate and still turn settings to high.
 

Ofc, if you’re running G-sync or Free-sync you’re mitigating this issue somewhat and can get away with an uneven framerate. 😊
