I am actually about as balanced as it can get right now with my 9900K and 3080, running at 3840x1600 ultrawide. My GPU runs at 100% and I have those one or two cores on the CPU pegged as well. I am capped at 60 FPS unless I am over a large city or large, detailed airport, in which it sometimes goes as low as 40-45. I don't need a bunch more FPS, but I would certainly take whatever it'll give me, especially if it means I can leave ultra clouds enabled at all times.

Was toying with i7 but based on this it sounds like the i9 processor is really making a marked performance difference?

Really enjoyed the livestream. Its so fantastic to see devs actually respond to real end user issues and questions. Now I know how important it is to use the official forums to ask questions because they do check. Jorg, Sebastian and Martial are wizards! 😃

I am most excited about the tree line fix as 99% of my flying is low level GA.

So DX 12 is postponed and they aren't sure now if it will even bring performance improvements to PC?

 

What's not to Love in this update!

They've been saying for several months now that DX12 wouldn't bring noticeable performance improvements.

This isn't new info.

The performance improvements are coming from better memory management and not running everything through the CPU.

The 9900K is really old news at this point. If I was building a rig now I'd go AMD CPU + Nvidia GPU. That's a topic for a different forum though.

It's the best news! 

[Ixoye 1,854]

Hopefully I can keep my 2080Ti and put my money on a high-end yoke instead of a new GPU, and maybe the old tree fix mod will work again.

I think I said this before, but usually a developer would be lucky to please maybe 2% of the Avsim readership?  That would be considered great.  Now, they're pleasing at least 98%?  ROFL.  They must have struck gold! 

It seems like our new sim is really gaining some serious steam (no pun intended). Can't imagine what the next year will bring. 🙂

Right now I play on Samsung 4k 55 inches 

With almost everything on ultra, I have about 35 fps ( RTX 3090, 32 GB DDR4, I7 9700K@5,1  ) 

What do you think, guys, do I have a chance to upgrade to 8k, in the near future? 

If I could get 25 fps, it would be okay for me

It all depends on how much you are limited by your cpu. You have the same cpu used on his tests, so you might see some gains. How’s the usage of your cpu/gpu?

@8k you will pretty much have no cpu bottleneck, but even your 3090 would be hammered hard. 

[Sphynnx 91]

I didn't check the CPU / GPU usage 

Another question about 4k vs 8k :

As I said, I play now on 4k 55 inches which is about 82 ppi 

If I decide to upgrade to 8k, I'd go for 65 inches, which is about 135 ppi 

The question is : how would the image quality be on 4k ultra settings, on 55 inches ( 82 ppi ) vs 65 inches 8k ( 135 ppi ) medium settings?

Just to explain sticking with DX11 for now,

Very minimal if any optimizations were made in the rendering path itself. The sim is architecturally separated into a renderer backend with a defined interface. For DX12 on XBox, the only thing being done is to make an identically performing renderer backend for a single GPU in DX12, which is a very well defined target. The story for PC gets a bunch more complicated because the GPUs are much more diverse, the drivers much less well behaved, and the memory system totally different; on XBox you have shared system and video RAM which makes for totally different allocation strategies than you might use on PC. The DX12 render backend for PC is not yet fully baked and needs more time on more hardware.

However, basically all of the optimizations have been done prior to the backend. Therefore, PC users are not at all losing out. I just want to stress this: DX12 is not a feature on its own, and XBox is not using any features enabled specifically by DX12 yet, either, like raytracing.

It's obviously pretty hard to promise universally amazing results on every piece of hardware out there, but I think most people will be very, very happy with the performance and memory work.

I’m not a specialist but in my experience, those things (ppi and resolution) are more noticeable on smaller screens (like a 23”-27” PC monitor), because you sit and use them closer to your eyes. 

[Sphynnx 91]

135 ppi it's a lot 

Even on 65 inches, everything should look clear, generally speaking.

Something like 32 inches, 4k

By the way, few years ago I tried a monitor, 32 inches, 4k

It was absolutely fantastic, but I didn't keep the monitor 

Way too small..... 

That's why I'd like a bigger screen

If I go with 65 inches, 4k, it's a bit.... pixelated, so to speak

It is worth pointing out that the big improvement in the videos is because the PC in question is CPU limited and they have done a lot of CPU optimisation, and in particular moving processes off the main thread to share the load a bit.

People with good GPUs and lower end CPUs should see a massive improvement.  

People with high end CPUs and older GPUs - maybe not so much.
