From what I’ve tested, heavy Windows games don’t run well on Remix OS unless you go through Wine on Android-x86, and even then performance is hit-or-miss because of DirectX limitations. That’s why most people stick with games that are natively optimized for Android they run smoother and don’t need extra wrappers.
One good example is Manok na Pula 🐓 — it’s not graphics-intensive but surprisingly addictive with its PvP battles and upgrades. Since it’s designed for Android, it works perfectly on Remix OS without any tweaking. If anyone’s looking for something fun to play while experimenting with emulators, this is worth a try manoknapulapk.com
