I do assume things based on performance based on the engine, but that’s more for moments like "new game is coming this fall, using some engine ", before tech specs are out. I find a lot of games that care to announce an engine in any way tend to be the heavier resource hogs, because they’re advertising the high fidelity of something-or-other.

But that’s not really a condemnation on any games. I do often avoid the high resource games, but that’s because I have an older PC, not because of any actual prejudice against an engine itself.
