@All
Is anyone use this kind of card on amigaos4 ? I buy today "MSI AMD Radeon RX 570 ARMOR OC 8 GB DDR5", and notice 2 issues with it at moment:

1). Sysmon show for graphics card that:

Card Name : Radeon RX Polaris10
Free mem: 217mb
Used mem: 25mb
Free GPU: 7936
Used GPU: 0
Total mem: 4082 mb

So while i have 8gb of GPU memory, it still show that total mem is 4082, and when i fill GPU more than on 4gb by data, it then behave badly and give visuall distortions.

Is it expected that only 4gb of GPU memory are usable ?

2). While simple tests works (like filling of video memory by data), or Warp3DLogo works. The other examples didn't works. For example if i just run "W3DNBitMapCube", then nothing happens and on serial i have tons of that:



Then i tried debug version of RadeonRX driver, and that what i have if for example run "W3DNTextureCube":



That all on RadeonRX 1.12.

Tried also versions 1.10 and 1.11 : the same results.

I tried then and without compositing, and without interrupts : all the same.

Tried also with some previous version of warp3dnova : still the same.

Anyone tried such cards ?

Created 2 bugreports about:

1
Non working in 3D when it more than just some simple things:

2
Only 4gb of 8gb of extendent GPU memory can be used:

@all
Second issue (crash when we fill more than 4GB of GPU memory on RadeonRX) are fixed too. Currently testing it, but it works, so once it released you will be able to use whole 8GB (if any amigaos4 3D app will ever need 8GB of GPU memory, but never say never :) ).

@kas1e

if you do lots of picture stuff with e.g. Multiviewer you'll pretty soon fill up any amount of gfx ram, so the more the merrier
