Only 256MBs ? So how much XDR system ram should it have come with ? Perhaps a 320/192 MB arrangement ? So we'd have better textures but less complex programs ? Or was Sony supposed to include 320MB or more of VRAM while maintaining the full 256MB of system ram, just tack on another $50 at launch ? It already started at the astronomical $500 and $600 price points. Remember X360 was originally planned to only have 256MB total.
From what I gather, this isn't even a GPU memory problem. If it was, it would have been simple to dial the graphics (textures) back, to free up more memory, and the problem would fix itself. It's a database problem. And if they were that tight on memory, they should have compromised something else on the PS3 port just so the damn thing can be played without dropping to 0 FPS walking down a path. LOL
It's not slowing down because the GPU is overworked, it's slowing down because it's a game built on ancient legacy code with a PS3 compilation which is fundamentally unsound, leading to severely degraded performance over time.
I think your argument that Sony bears some responsibility for Skyrim's poor running state, because PS3 hardware is so "weird", is ungrounded. PS3 needed its own project manager, with expertise. It was obviously not optimized if the game ends up a stuttering slide show. Apparently FO3 PS3 and GOTY had the same exact issue.
The series earns enough money, they should have done it right (preferable) or not done it at all. I'm not so sure the actual game programmers at Bethesda wouldn't have liked to try and fix it, call in Sony ninjas or whatever, but maybe the corporate suits said fuck it, ship the PS3 version broke, we don't want to spend the cash. And if that's the case, they should be sued in court and forced to pay damages. It's really no different than any other defective product. It's against the Uniform Commercial Code.
