Black Mesa (2020) | Full Game Walkthrough Part (4/4) [END]

Regarding the performance issues, as you can see in the last part of the clip, it sometimes gets laggy and sometimes runs smoothly. Once again, this is all because of the heavily pushed Source 1 engine. That’s also why I kept quicksaving like crazy on the elevator near the endgame, including the boss fight, that section is extremely prone to crashing to desktop. I’ve experienced it multiple times already. Overall, the game has beautiful graphics and a much larger, expanded gameplay experience. The only major problem is the engine itself. If it had been built on Source 2, this would easily be a perfect game in my opinion.
