Finally! And it’s already looking great.

Omg, one of my favourite PS1 games!

Lol, here's everything you need to know about it and download: wiki.special-k.info

Correction: it's being ported by both Iron Galaxy and Nixxes. Interesting.

Using Special-K to cap the frame-rate fixed those spikes for me.

Tutorial level is very much GPU bound. The bottleneck shifts to towards CPU once you enter Vatican with Full RT on. It's super heavy on CPU. I imagine non-X3D Zen 3 for e.g. will likely see dips well below 60fps, even though GPUs like the 4070 and up would be capable of more.

That's a generational leap.

However, I'd wait at least 6-8 months before putting the game on disc, allowing time for all updates and patches with bug fixes to be released.
