@geennaam
but anyway I will test the WaZp3D with compositing - at least on the card stayed on my Sam - R9270X.
On MorphOS I have better results on R200 cards with WaZp3D instead Warp3D. But is not comparable with AmigaOS - here is Warp3D native, and on MorphOS it is wrapped with Goa.
But comparison will be interesting too.

@geennaam thank you. Unfortunatelly I had only one Polaris card, and this one was not works. Maybe one friend lend me another one. You very brave that you understand the google translation from Czech language - it is really not an easy task! For example "X-Ray driver" from google is very cute. All Southern Island were tested with Warp3D-SI. WaZp3D with compositing not tested, but it is also good idea. I only test Southern Island cards both with MiniGL4GLES and MiniGL. MiniGL4GLES was a little bit faster - 43 vs. 46 FPS WingBattlefield on R9 270X.

@mr2:
I see, that on hdrlag.org.nl your HD7750 card is described like "Radeon HD 7750 1024MB GDDR5, PCIE 3.0 SingleSlot" - not only HD7700 series.
Please, how do you changed it?
I want to write exact description to my cards, but if i click "(Details above incorrect? Submit a correction)" on card result page, write the datails + "Submit", allways get Server Error.

This card also not works in AmigaOneX1000. If I find somewhere Radeon RX card which works for sure with RadeonRX on Sam460 or X5000 - for example Kas1e's RadeonRX 560 - I will try it on Sam440ep-flex. So, next time...

@mr2 Did you try kas1e's version of Odyssey? Odyssey and Bookmarks #11On AmigaOne X1000 it works perfectly, but with my Sam440 (733MHz) there are framedrops. Good enough for listening music, but for videos it is far from ideal. Maybe if you have 800MHz it will be better.

I tested my RX460 with previous driver version. I will try with the new one and post here the debuglog, but probably next week, now I have very little time.

@geennaam
yes, I know that the priority will not be high.
It is excellent, that Southern Isands now works on Sam440. It have Warp3D and 3DNova. The RX - Polaris card have only one advatage - UVD. But who knows, maybe there will be UVD for Southern Islands too.

@kas1e many thanks! It works very nice ! Excellent work! Your video about soundblaster utilize CPU on AmigaOne X1000 only by 30-50%. On Sam440ep-flex (733MHz, but with R9 270X ) utilizes CPU by 100% with some framedrops, but it is still playable with good sound.

@geennaam Quote: From what i've read in other threads, the RadeonHD driver tries to improve memcopy speed with changing settings in PEX811x bridges. So maybe that's the source of the issue. It was reason for me to try another bridge. I think, you are right. I check the debug output, and with use of PEX8111 bridge, there is allways error with AtomBios
RadeonHD (0): ERROR: AtomBIOS is stuck in a loop for more than 5 seconds. Aborting
RadeonHD (0): ERROR: AtomBIOS stuck executing C302 (len 321, WS 0, PS 4) @ 0x0072. Aborting.

then Radeon recognized correctly conectors and connected monitor, and black screen. With PI7C9X bridge Atombios works normally.

@geennaam Quote: But I have to disappoint you. Someone else uploaded a >25% better result today as well. (Wasn't me.) It was me. According your advice I tried other PCI-PCIe bridge - P17C9X 111SLBFDE. The card is Powercolor Devil R9 270X ( borrowed from my AmigaOne X1000) and my Sam440ep-flex is 733MHz version. This card is dual-slot and 180 TDP, a little bit overkill for little Sam . And I have no succsess with PCI-PCIe bridge PEX8111 (and have no 8112).
