Most games does not care what GFX driver you have, its game engine that cares,

That's from the surface.

AMD RDNA GPU's integer has expected full-performance 24-bit integers and degraded 32-bit integers performance.

You can see different datatype performances on different GPU hardware implementations via AIDA64 benchmarks.

RX 7900 XTX (gfx110)
FP32: 60,647 GFLOPS (Wave32's dual-issue mode is active)
INT24: 32,632 GIOPS
INT32: 8,308 GIOPS
For data load-store functions,
TMU counts around RTX 4080/4080 Super level.
ROPS counts around the RTX 4090 level.
RX 7900 XTX's raw compute is about RTX 4080 Super level.


RTX 4090 (AD102)
FP32: 101,936 GFLOPS
INT24: 51,070 GIOPS
INT32: 51,169 GIOPS
Half of CUDA cores support INT.

Coupled with RT implementation differences, modern games can be biased towards certain hardware architecture.

Depending on the game content, you can make Unreal Engine 4/5 to be biased towards AMD or NVIDIA e.g. heavy RT workload content would gimp on AMD GPUs. You can gimp AMD GPUs with heavy INT32 shaders.
AMD would need to intervene with their monthly driver updates that target specific games.

Both NVIDIA and AMD have monthly driver updates that target specific games.

My point, it depends.

The software abstraction layer has limits.

AMD never delivered AD102 class GPU for consumer markets since MI300's 220 CU scale runs on older GCN 5.x (Wave64). AMD has changed direction with UDNA. Lisa Su has f__ked up AMD's GPU approach.

OS 3.x has perfectly usable 3D on Parmedia and Voodo 1-3 cards
Also Radeons 9200 to 9600 are more usable on OS 3.x then on OS 4.x

Where do you use those boards on 68k?

Ancient cards that nobody even uses on OS4. Great argument.

What does everybody use on OS4 today?

Radeon RX560 and RX580 seem to be the most common choices these days.

Well I started with an ATi 9200 in Picasso96 on my A4000 via a Mediator PCI daughter board. Then I upgraded to a Voodoo 3. And then I moved all that to my backup A4000, after I got the ZZ9000 for the main A4000.

Running everything in high colour at 1920 x 1080 is very cool, and having AGA modes passed through and flicker-fixed is very convenient.

I don't care to play ports of PC 3D games from the '90s. I wouldn't do that on any of my Mac, Linux or Windows machines either. If I have time to play games, I'm playing games from the last several years, and on the very rare occasion classic Amiga games on the A4000, which only has an 040 40MHz.

But I know many people do like playing those games, and they like the added challenge of playing them on an Amiga. Which is why I'm looking forward to the day when emu68 or some extension will give OS 3.x and AROS 68k users full 3D access to the GPU in the Raspberry Pi 4+.
That way, they can play these titles via their beloved OS on their favourite 32-bit big endian architecture without spending thousands of dollars. And ppcamiga1 will hate it.

Now that's a bounty to which I'll happily contribute.

That cant be used on x1000, dont display signal on soft reset,
need 100 euro drivers and enhancers and are half used compared to Win Lin

Card shipped with x1000 never got 3D, when I got Southern Island
3D was opted out Linux.

I would be better with ancient R9600 or model in my iMac G5

I guess 2D wise there's shouldn't be much of a difference

Nice, I was under that impression, I even talked about it elsewhere, but couldn't pin point exactly.

That would be sweet indeed!

But that would be even sweeter! xD

Would this board be any use for future development of OS4 - Milk-V Jupiter RISC-V PC Build

@Deaths_Head

Nothing can help OS4 BUT using PiStorm and System54 ARM optimisations or having AROS ARM recompile x64 could be way of quick transition
