P3D v5 is DX12

Recommended Posts

Nice. Pretty much confirms what Rob has hinted at before on this forum.

Wonder what does this mean in regards to existing add on compatibility?

Yup, memories of the FSX DX10 preview come to mind lol. Personally I am really pleased to see that a new version looks imminent of P3d, even though I am on the MS2020 TA

FSX DX10 was buggy.. because Microsoft never finished it.. all the shaders were not working as they should, etc. and that was the biggest issue with it. Nothing to do with 3rd party add-on's.

People should stop worrying about 3rd party compatibility.. :wink:

Nothing at all. Direct X versions are all backwards compatible to Direct X 9. This was released in 2002, so it should cover anything you are likely to encounter today and yesterday,.

I am not on any beta or anything but was looking into some new software for my simulator when I stumbled upon this

https://fly.elise-ng.net/news/new-fly-elise-ng-4-2-1-software-release/

v4.2.1 (20200310)
– NEW: Build for 64bit Windows OS
– NEW: P3D v5 + DirecX 12 support
– NEW: X-Plane 11.5 + Vulkan support

I've been testing XP 11.50 beta for the last two days and my fps doubled using the Vulcan API. It made me wonder how long before P3D upgrades to DX12. I hope we see the same fps improvements.

Well that’s exciting! Maybe it’ll be just around the corner too 🙂 🙂 .

What advantages does DX12 bring over its predecessor? Visuals obviously but specifics would be nice.

It all depends on how the API will communicate with the GPU & CPU. I'm guessing that performance will improve. Don't know if it will fix the pauses or stutters. XP 11.50 with Vulkan enabled is silky smooth.

@DJJose, is Vulcan the XPlane equivalent?

On a more general note will scenery designers have to modify their products to benefit from DX12?

It is really debatable, several researches indicate both perform very similarly, here is one of many: https://www.overclock3d.net/reviews/gpu_displays/basemark_gpu_dx12_vs_vulkan_performance_review/4.. charts below:

29133307616l.jpg

29133257698l.jpg

They concluded:

At 1080p, we found that in most cases that the DirectX 12 API offered the best performance, with Vulkan coming a close second while OpenGL sat at a distant third. Basemark GPU's OpenGL performance on Nvidia hardware is leagues ahead of AMD, with the RX Vega 56 and RX 580 both offering Basemark GPU scores of around 4000, while Nvidia's GTX 1060 offered a score of 8470. As usual, OpenGL performance appears to be an Achilles heel for Radeon, but thankfully this API has been mostly depreciated. 

Cranking things up to 4K we see that most of our graphics cards offered similar results when using all graphical APIs, with OpenGL having major performance consequences on our Radeon graphics cards. On the Nvidia side OpenGL, Vulkan and DirectX 12 offered nigh-identical performance levels, offering minimal variance in most cases. 

-----------------------

So under 4K DX12 has better performance and at 4K the difference is so marginal that it will be not noticeable for end user, now what you need to understand is that converting from DX11 to Vulkam would be much more work than to DX12.. and DX12 has very nice features.. google Nvidia flow.. and ray tracing..

Vulkan is the successor to openGL. 

DX12 will be the successor of DX11.

Deduction: I guess so! 😀

@DJJose, haven't used OpenGL since Project Magenta days. Yes, I worked out the next bit myself. 😁
