Esenthel on XBox
Hi, I was testing my project on XBox One X using UWP, and I was able to sucesfully launch it. Saddly some issues occured:

- Performance is bad and Xbox tool shows that only 1 GPU engine (from 8 available) is used by game. With one source of light, low setting and small scene, fps is between 50-30fps. My game is set as Game (not App) so it should have full acces to GPU power https://docs.microsoft.com/en-us/windows...allocation

- XBox gamepad is detected only about 50% times when I run game, and it seems totaly random (gamepad works since I can use home button and navigate xbox settings)

Also, how looks possibility to add DirectX 12 support to Esenthel?

Screen from Xbox tool showing GPU engines usage:

RE: Esenthel on XBox
Hi,

Thank you for sharing your test results.

I don't have an Xbox so I can't do any tests myself.

Perhaps you could try:
-Make sure your Xbox has all latest System Updates
-try running game in Release instead of Debug
-perhaps setting as "Game" instead of "App" did not succeed?

I don't have any plans for DX12 in the nearest future, as it's a very complex beast, however my estimates are that it would improve performance only by a few %.

I've read on some gamedev forum, that I quote:
Quote:It does have 8 engines, but only 1 of them is 3D. Others include copy engine, compute engine, video decode, video encode, etc. For rendering only 3D one can be used. Games will probably utilize the copy engine a little bit too, and compute engine if you use compute shaders.
It's possible the other GPU engines, are for some other stuff, and not 3D rendering.

It's also a possibility that performance could be limited on Xbox if you're not a registered developer:
https://www.xbox.com/en-us/Developers/id
https://www.xbox.com/en-US/developers/creators-program
or perhaps because you're using a normal Xbox instead of a Dev Kit, I really don't know.

As for the gamepads, you could try some debugging:
-The engine always calls at the start "ListJoypads"
https://github.com/Esenthel/EsenthelEngi...d.cpp#L554

-It also registers callbacks for gamepads added/removed:
https://github.com/Esenthel/EsenthelEngi...m.cpp#L136

-Which again call "ListJoypads"

Perhaps you could try to see why "ListJoypads" doesn't detect your gamepad successfully.

Thank you for your reply.
My Xbox has latest update, I'm am registered developer and I have dev kit. I'm sure project is set as "Game" since I can use more than 1GB RAM. Running game as release don't help much.

Quote:It's possible the other GPU engines, are for some other stuff, and not 3D rendering.
Hmm, it could be true, but still I belive I should have better performance anyway. For now I will make more test and try figure something out by myself.

About gamepad I will try some debugging, thanks for some tips.

And true that adding support for DX12 wouldn't add much performance rise on PC, but on XBox it would make difference. But I get that it would cost a lot of work, and you have other priorities right now.

Also what monitor /TV resolution do you have? You can use D.density to force rendering to a lower screen resolution which can give a performance boost
