Just got shipment notifications for PS2 and Wii HD Retrovision Component cables and RetroTink 5x!
Really gave up on getting decent performance out of PCSX2/Dolphin - it's fine most of the time, but the random stutters do get annoying. RPCS3 and CEMU work basically flawless, so there's something in the settings I'd have to figure out (powerful PC + same behavior independent of graphical fidelity = misconfig somewhere, but I've had these issues on 3 PCs throughout the last decade, so maybe I'm just a bit too sensitive, or I'm choosing to play games with poor compatibility), but I prefer original hardware anyway since it just works.
Was kind of hesitant at first, but I think this should be a close second best option for playing GC/PS2/Wii games, only slightly behind an actual CRT. Even then, I'd have to get a decent (= large + expensive, most likely) one, which is in no way easier than just getting an RT5X.
Finally I'll be able to properly display 480p content, since my TV is hell-bent on squeezing it to be ever-so-slightly narrow. Funnily enough, my PC's 4K monitor handles these signals well enough. Other than that, really looking forward to trying motion adaptive deinterlacing, since my TV's deinterlacer introduces obscene amounts of lag. Looks pretty, but at what cost!
