It won't help much if you're GPU limited, not sure if that's your case. It depends on your hardware; if your CPU outperforms your GPU (e.g. you have an older GPU), the improvements in CPU usage with DX12 might not help much. 

 

These are my specs:

Intel Core i7 12700K (5.0GHz Max Boost Clock) 12-Core CPU   32GB G.Skill Performance DDR4 SDRAM 3600MHz       Graphics Processor:12GB Nvidia GeForce RTX 3080 Ti, GDDR6x System   2TB Western Digital, NVMe M.2 Solid State Drive

Oh yeah, forgot about that one. I have to do this every time I start the sim, otherwise I'll get SDR. 

This is one of the things they didn't fix in the for the release. It was discussed at great lengths in the official beta forums. 

I recall that this may have been an issue in W10 but not in W11 which deals with HDR a lot better.  I can certainly remember having problems in W10.

I would definitely give it a go. With DX12 all those 20 threads will be utilized. This is one of the advantages of DX12 as I see it - CPU utilization is way better than with DX11. Might as well get your money's worth for that Alder Lake; it's an excellent CPU. And I'd consider running Win11 as well (if you're not) due to the improved thread director with Alder Lake.

I really like the DX12 ( icw Gefirce Experience filters )

I think your cockpit setup is incredible, Gerard. Truly a labor of love.

Just one question. Does you wife, girlfriend, etc. think you are crazy? 🤣

[andrevieira 16]

I use a RTX 2070 Super.

I did several experiments between DLSS (quality, performance, ultra performance, and with AMD sharp values of 0 and 200), and almost always the same FPS, regardless of whether you use quality, performance, ultra-performance, sharp 0 or sharp 200. It just varies 1 or 2 fps.
Then I retested TAA with 70% render scaling, and the FPS continued the same, but not so smooth, i think.
This, with the DX11.

Honestly, I don't know what to use.

he doesn't have one. one expensive hobby is enough. priorities.

That's a good choice.

I have a sticker on my boat that is a constant reminder to me. It says, "If it flies, fornicates*, or floats, it's cheaper to rent it."   * - you know what it really says

Yep, sometimes my wife thinks that I am crazy. 
Then I say : what would you like better ? Me staying at home in the cockpit or me going out with friends every Friday / Saturday …🥳

or who would ever want to go out with his own wife every Friday/Sunday. absurd idea.

Mostly benefits newer RTX2/3 series with DX12?

I am still on 1080TI waiting for a new build still.

Diskcleaner for shaders shifting between DX11 and 12?

Thanks Michael Moe

I'm on 1080ti still and just tried dx12.  Runs smoother for me. Only gained a few FPS but its a lot smoother and i was able to run LOD slightly higher. I saw try it with the new studio drivers.  I'm not going back to DX11.

Same. I see no reason whatsoever for that. However, many are reporting higher VRAM usage with DX12, and some are pointing out the risk of exceeding available VRAM, leading to RAM being used, with much lower latency. So it's probably a good idea to have a look in dev mode if DX12 is not giving good performance. If VRAM usage is too high - lower the settings.

Or get a 3090/4090 😄

Which might be the most demanding settings for VRAM?

Texture resolution ultra, 4K resolution with increased render scaling.

Shadow maps at max seem to use a bit more, but not that much.  

I just tested and clouds, terrain and object LODs doesn't seem to impact VRAM much. Having a TLOD of 10 or 400 and GPU mem is about the same, reported by dev mode.

Just tested the effects of texture resolution on VRAM:

• Low: 8.5GB
• Ultra: 11GB

Same airport, all other settings the same. Just noted "GPU mem" in dev mode just after loading a flight at EGKA. 

Hence, if people are struggling with DX12 and VRAM being excessively used, leading to stutters, the most efficient way to lower VRAM usage could be to lower the texture resolution.
