PCem relies on a dynamic recompiler for fast performance, and emulation speed depends on how a particular game utilizes the emulated CPU. With one game, I might be able to run it on a PII-450 at 100% speed (and still room to go higher), while another game might max out at 100% CPU time on a PII-300. Some tips, tricks, and other observations:Įmulation performance depends entirely on the game/software being run. I’m mostly interested in the upper end of PCem performance. I am still testing things out so I’m probably missing a lot.īy the way, my main host PC is an i7-12700, 32 GB RAM, RTX 3060, Windows 11.
Also, if you notice any wrong info in what I’m posting here, please correct it. I’d love to hear more about anything related to maximizing performance, avoiding bugs, and so on. If you have any tips for using PCem, please share them here.
Unfortunately, I don’t think these have been compiled anywhere, so I wanted to create this thread as a way to share some. There are a lot of tricks to PCem that I’ve discovered by reading various things online. Like a lot of people here, I’ve gone down the rabbit hole of trying to measure and optimize performance. I’m a relatively new user of PCem and absolutely love it.
