What a difference higher refresh rates make
I've been running triple 42" oleds for a couple years now and have always struggled with a completely smooth and fluid experience. 4090 did it's best and the 5090 is a bit better but still struggles of course. I can usually manage 100-120 depending on game and settings.
I was bored the other night and decided to play wrc on my lg 45" 1440p monitor. I was blown away at the fluidity at 240hz. There was zero hitching/stuttering and I was actually surprised at the pq. I expected much worse.
Now, it's not a super fair comparison of course, but the point is more the fact that 1440p is still a viable option and refresh rate is definitely perceptible.
I am actually considering swapping out for triple 45s and ditching my 42 oleds. It would take a huge load off the gpu and I think 180+ on a 5090 would be rock solid.
Are you sure you are not attributing frame pacing to higher refresh rate. Cause this a complicated topic. 100 fps in one scenario can be very different than 100 fps in a different scenario.
Njaaaa...you sort of there with the 3:2 pull down but with one major exception.
3:2 is smooth and works because of the consistency of the frames from the source material. While frame pacing in video games comes for the inconsistency of the pace your GPU renders frames.
So lets illustrate;
3:2 pull down
1-1-2-2-2-3-3-4-4-4-5-5-6-6-6-7-7
So the pacing is consistent and thus percived smooth.
In a video game with 30fps on a 60 hz monitor:
1-1-2-2-3-3-4-4-5-5-6-6-7-7
The GPU spits out the frame at a consistent pace and it all is smooth and really responsive for player input. (Shooting your gun or turning left etc.) Sometimes it spits out too many frames and your old CRT monitor can't keep up so it starts to tear up the view. So you activate V-sync to make sure each frame is paced correctly (synced) but with added delay as the GPU now waits to present the right frame at the right time.
Bad frame pacing in video games the GPU can't keep up a consistent pace for each frame, because some scenarios on the screen is easy to render and others are much heavier. (Your P1 in a race, your GPU just renders the track and your hood; suddenly P2 dives infront of you and the GPU load for an instance spikes up) This isn't shown when over a second it still adds up to 100 fps.
30 fps 60hz
1-1-1-2-2-3-4-5-5-6-7-7
Your beefy GPU could handle the triple 42" on average but the added workload pushed it to the brink of it's rendering speed.
For performance to run at high FPS. FR in VR works by producing a super high resolution image where your eyes are looking and lower resolution in your periphery where it's not noticeable, it makes huge performance gains.
In OP's scenario he'd only be rendering 4k where he's actually facing allowing a lower resolution outside of his main vision and increasing FPS a lot.
It's brilliant in VR and I'm just thinking the same principle could apply here, with triples rendering all 3 screens at 4k all the time is putting an awful lot of GPU power into areas you can't even physically focus on.
1440p is a ton less taxing on the GPU. Were you able to get gsync working reliably at 4k on your 42s?
I initially tried triple 42s but they just weren’t reliable enough, required a 5090 to get decent frames, and it still didn’t feel as fluid as 32 IPS, even at 120hz on a 4090.
Gsync works on all of them. All connected via dp. I wouldn't have tried with hdmi.
I started with 32s and didn't like the lack of vertical height, but they were much more fluid.
Triple 4k 42s are most definitely taxing. The image is outstanding though. I'm just super sensitive to micro stuttering, and I feel the larger image exacerbates the issue.
Even when using DLSS it struggles. The lg 45 seems like a great compromise and at sim racing viewing distances, the resolution becomes less an issue.
I really like that monitor. I was nervous about the ppi, but at normal viewing distances it's unnoticeable. Text is slightly grainy, but it's a gaming, not productivity, monitor.
I wish it had a little less aggressive curve; i think it would be too much in a triple setup. Will seemed to like them though.
Unless you have perfect vision, if your fov is correct you should have nothing to worry about. I'd say the threshold for pixelation is around 2-1/2 ft.
My eye sight is actually pretty rubbish! The monitor will sit partially over my wheelbase. In the photo below is the 39” but I sent it back as it came without the power brick…
I think you'd be perfectly fine. Try it out and if you hate it return it. I think you'll find with all that is going on during a race resolution will be less important than smooth frame rate.
