Do 4K users need NVIDIA 3080 ???

I'm going for the 3090 mainly because of the 24GB of VRAM and since I fly at 4K Ultra, it will surely help me get there.

 Yes for 4k I agree you need 3090 to keep you happy for a few years.

I'm hoping it will keep me happy much longer than that. Especially when I'll be spending $1600+ for a GPU. lol.

I’m on a 2080ti currently with 3840x1600 and 32Gb RaM with i9900KS 5GhZ water cooled. 
I can get super smooth on ultra as long as I reduce the LOD to 100. As soon as I move the slider to 200, I get stutters. 
 

PS I assume this is because I become cpu limited, as mainthread flashes Up for a split second when the stutter happens....... so, even if I dump a 3090 in, I assume I’ll still have the same problem right?

 Run a game at 1080p on medium and you will likely be CPU bound.

Why is that? Is it because the gpu has to much energy and cannot forward it because of 1080p doesn't know how to handle it?

I reckon the 3090 could run at 8K 30 fps.

This may be a useful video to watch. Especially when he talks about the availability of cards. Some of you may be very disappointed or at least frustrated by the wait.

Something is always a bottleneck.

As you lower resolution the GPU has less work to do (shading, anti-aliasing, super sampling, ray tracing, lighting) so the frames go up and up until the rest of the system cannot support the higher framerate. This is often the CPU but can also be RAM, motherboard bus or even disk IO performance.

A nice feature the 30 series has is RTX IO https://www.nvidia.com/en-us/geforce/news/rtx-io-gpu-accelerated-storage-technology/

This promises to be able to load data from an NVMe drive directly into the video cards VRAM bypassing the CPU and RAM. It is possible this could be quite beneficial for flight simulators.

Quite true on my system. When I get stutters it's always my CPU maxing out, not the GPU.

Exactly everything has a bottleneck that prevents it from running even faster when it comes to gaming.  In practice there is a practical limit to framerates and what we can do but this even gets pushed further (See 360hz panels now) but something will slow it down.  Just a fact even if you run an old game on a new PC there is something causing it to hit some practical limit.

I think the answer is both yes and no.

I have the same setup as you and I have see areas where I am CPU bound (dense cities, loading new areas) and other areas where I am GPU bound (lots of reflections and cloud lighting).

So you will certainly have some areas where you get an increased framerate where its smooth but many of the big stutters may well remain sadly!

A 4k OLED looks better than 8k non-OLED.

Sorry, but this video is totally non-sense. OLED has the following two major advantages:

- Nearly perfect black level

- Very fast response times

The comparisons in this video, especially the image and color quality have nothing to do with the technology. I have seen recently a video where a Sony IMX219 lens was edited and created nearly the same colors as a 4000$ Sony camera. 

4K, 8K will just be what 16K and 32K will also be, just for profit and milking your money. 

[bean_sprout 1,201]

Make sure to watch the end of the video or you won't get the point of the video,  The other plus of OLED is power consumption because unlit (black) pixels are turned off.  Also less heat.   As you would expect black level / contrast is fantastic like my old 21" NEC CRT. 

I owned an OLED and will buy another.

Oh OLED is very impressive technology so is HDR IMO I feel like greater color color and contrast is going to be a bigger boon to display technology then higher resolution displays at least for the immediate future.
