though we may be limited by PCIe bandwidth limitations of course. Possibly playable frame-rates on some of those earlier 1080p games? I'll likely be testing with an RX 5700 or 5700 XT - the closest GPUs available that match PS5's rendering power. Me? I'd be happy with full-speed emulation - and improved adherence to frame-rate caps. It's all about 60fps and higher resolutions, improving upon the original experiences. I'm not expecting miracles but at the same time, a lot of people have higher expectations from RPCS3 than I do. I'll learn more once I've tested some more. Removing SPU post-processing also seems like another strategy employed by some of the patches. I've observed that some of these RPCS3 patches disable MLAA on SPU, resulting in dramatic performance uplifts - and this suggests that SPU emulation hammers the host CPU (I may be misremembering here but I dimly recall MLAA requiring 25ms of processing time across six SPUs).
But I'm also pretty sure that some patches may be required, short of a revelatory increase in emulation efficiency. Of course, the objective is to suggest that maybe PlayStation 5 could emulate PS3 titles, that there is a route forward for official, emulated back-compat. But what else should I test? Killzones and God of War seem obvious, but what other titles stand out? Suggestions below please but in addition to the title, please explain why it should be tested! The logical end point will be The Last of Us - the last great hurrah for the system.
Not flawlessly, not quite, but enough to prove the point - the CPU barely hits 20 percent utilisation. I've started with Ridge Racer 7 - launch game, 1080p60 - and even with the supplied RX 550, it runs fine. The question is: what games should I test on it? So there's no need for hacking a PS3, which has made life easier. However, I have installed Windows 11 on it, I have sorted out RPCS3 and I even have a supported Blu-ray drive attached that allows me to dump off my PS3 BDs - it's the same drive I bought many years ago so I could snoop at the file structure of any given game (standard BD drives don't allow this).
The picture above shows the Ryzen 4700S desktop kit - a bizarre abomination to be sure, based around the PS5 APU but neutered 'thanks' to its awful connectivity and dire PCI Express slot bandwidth.
