As an engineer, it's unbecoming of me to call technology "black magic", but this definitely fits the bill. While it can't generate performance from nowhere (you still need enough power to run a game at Low settings for upscaling and framegen to get you anywhere), it's absolutely amazing for upscaling older games to high-resolution monitors. Playing Total War: Shogun 2 and Resident Evil: Revelations at 4k120fps is an absolute dream.

A gruesome and erotic horror game, a heartwarming harem series about a sweet boy whose blood can cure the 'maidens' of demon corruption, and a polished dungeon-crawler. It's essentially a grimdark Persona with the romance cranked up.
