That Time Crisis 2 link up seems to work ok. Again, it's a bit slow on my laptop though, but then a single instance Time Crisis 2 running is a bit slow! It was apparently tested with an Intel i7-12850HX and AMD Ryzen 9 7950X3D. I don't think you need anything quite that fast to run it but I reckon a pair of fairly meaty PCs and you'd have a decent alternative to original pcb sets.
