DRE is an absolutely worthless gimmick. Even SSDs which are way faster than the fastest UFS storage used in smartphones can’t be a substitute for RAM. ZSWAP was pretty similar if not identical in the Linux world earlier and it was used by Android custom kernel devs as well but it was mostly deprecated sometime back presumably as it’s benefits were marginal at best. There is no substitute for RAM. Chinese OEMs can be depended upon to hype meaningless stuff.
Helio G95 is quite under-powered to handle BGMI but there were folks who actually played PUBG in devices powered by the woefully slow SD430 so… It depends on what one considers tolerable I guess.
