The warning is also irrelevant.
Yes I know the problem is still occurring.
I've asked AMD to investigate because I don't see any problem on the engine side.

AMD was able to reproduce the bug and it was sent to their internal driver team for further investigation. I was told even if they confirm it as a bug and fix it, the driver may take few weeks/months until it's released to public.

So once I finish PBR, I will try to make a workaround for next release.

I've just uploaded a new engine version with a possible workaround for AMD problem.
Could anyone with AMD card please test it?
Thank you

1)
I use this code to detect AMD card, could you please tell me if when putting this code into any of the tutorials:

Code:

Bool Init()

{

  Exit(ContainsAll(D.deviceName(), "AMD Radeon", true, true));

  ...

Does it properly show 1 (and not 0) on your computer with AMD card?

2)
I've just uploaded another workaround, could you please try the newer version?

Good news

I have the latest version on my laptop that runs AMD (i had huge artifact in the last update) and it is now working well, im not 100% sure about the text itself, but so far everything seems normal.

The only issue i have so far is with my Nvidia, the deferred render in the editor is flickering like crazy with artifact that stays about a split second.

happens with any material when i look at it in the editor, and same with anything that uses that material ( world, obj ... ).

In the game itself tho, it is perfectly fine, it really only happens in the editor

thanks for letting me know smile

the flickering on Nvidia is probably a bug in the driver, I'm guessing related to Render Target Discard.
If it's get too annoying or other people have it, perhaps I could temporarily disable it.

I've reported the bug to Nvidia:
