Need MORE performance for VR! DX12/Vulkan?

[0010101011011100000101010100100]

Have Oclus Rift-S and AMD Vega64 8 GB HBM2... and the game isn smooth.
(12 Core TR2 and 128GB RAM, M2 NVMe SSD)

Generaly its so cool in cockpit but we have more or less lags and microstuttering.

Even with lower settings. AMD Lagfree helps a little bit.

But what really helps can only be DX12 or Vulkan support.

I would pay 10$ only for this API!

Vulkan is under development. Let's have a patience. 3 or 4 years and maybe we will get it.

Actually the game does not wand multi-CPU computer. The 4-cores CPU is enough. Much more you need the high IPC instead the number of cores.

Still, I have the Core I7-6700K and GTX 1080 and my bottleneck is still more GPU than CPU. For resolution 1920*1080 it is very good. You will get 100+ fps with no problem. But on my display with resolution 2560*1440 I have around 60 fps.

To get rid off the microstuttering the Gsync or Freesync display is actually the best solution. The microstuttering is mosty caused by Vsync when the FPS are dropped to the closest synchronous FPS (from 60 to 30)

LOL thx what a hope... years hopefully not!

Multicore counts only if we get the low level API.

I play meanwhile only with VR Ocolus Rift-S. You cant fly in real and you cant fly in milsim it you cant see deep. So in result i have 2K Resolution.

But even on my 5K 32:9 Freesync2 screen its better then in VR. Less microstuttering.

In my opinion the only was is DX12 or Vulcan! And we need it now!

Actually the DCS runs on DX11. Also the DX11 works better on OS supporting DX12 than DX11 only supporting OS. So in Windows 10 the DCS runs better than in Windows 7 and older.

It is important to put your demand (and it is indeed a demand) into perspective. DCS as a platform was built on top of some rather old tech. Over the years, Eagle Dynamics has worked pretty hard to update and renovate what they can but that work is slow, expensive, and can potentially create friction with their third party development model if not handled carefully. It was not too long ago that they pretty much updated the entire graphics engine to DX11 and even now they are working on Vulkan. This is going to take time and patience on the part of the players.

The other problem is VR. Like it or not, VR is still in its early stages and DCS (like many other games) is not built for VR from the ground up. VR is demanding on a hardware level to say the least and when you mix that with DCS's already high hardware requirements (due to its nature as a sophisticated simulation of large scale), it is going to create predictable, understandable performance issues. It is important to understand that the foundations that DCS World is built on were not constructed with VR even remotely in mind. Adding VR functionality at this stage (when its hardware requirements are already high outside of VR) will produce sub-optimal results (to varying degrees based on one's system).

Like it or not, you (and everyone else who is getting into VR now or already has a headset) are a early adopter and it is going to take time for titles that were not built with VR in mind to find ways to make it work well. Patience is key. You are asking a very, very demanding game to run through a very, very demanding platform (VR). The resolutions you are looking for and the performance you want will be difficult to achieve to say the least. It is the price of early adoption.

Thx to you intelligent comment.

You are absolutly right. But I cant wait. I will try to reduce the overhead if i play DCS complete in RAMDISK.

I will get you the results soon!
