Developer blames "potato" Xbox Series S for locking Gotham Knights at 30fps on consoles

I get the resolution doesn't help

Why wouldn't it? Having to draw 1/4th the pixels most definitely helps a lot. It requires precisely 1/4th the GPU power. All these geniuses had to do was limit resolution or adjust their dynamic resolution to lower values. These things have been figured out like half a decade ago. Yet they blame the console for THEIR games' issues.

I've had many cases when lowering the resolution didn't increase my FPS by more than like 5% when I was CPU limited. This might be the case here.

In the now-deleted tweet, the developer (who's actually a character technical artist at Rocksteady, not WB Games Montreal) mentioned the GPU being the issue. It's definitely nowhere near the capabilities of that in the Series X or PS5:

FP32 max throughput (XBSS vs XBSX vs PS5 - TFLOPS)
4 vs 12 vs 10

Texture fillrate (GTexels/s)
125 vs 380 vs 322

Pixel fillrate (GPixels/s)
50 vs 117 vs 143

Primary memory bandwidth (GB/s)
224 vs 560 vs 448

I also suspect that the triangle setup rate in the Series S is much lower, probably around half, than the Series X. But that said, Fleur Marcy (Exec Producter at WB Games) did specifically say that "it's not as straightforward as lowering the resolution and getting higher FPS".

Given that there isn't much difference in the CPUs, but there is with the GPU and memory sub-systems, I suspect that it's a combination of things like triangle setup and memory read/writes that's the issue here, which would tie in with her comments about the focus on the game being a 'fully untethered co-op open world.'

What's that? Consoles suck? You don't say.... :laughing:
