I found that setting the game resolution in version 5.1 was ineffective, and I could only use the maximum resolution. After updating the engine to 5.6, I discovered during packaging tests that setting the game resolution worked normally. However, in 5.7 it didn’t work again. I suspect it’s an issue with the latest 5.7 build packaging program because during this packaging test, I found that it didn’t package my localized languages (some of you might have encountered this problem too, which I managed to fix). But for this setting—the global game resolution—I don’t know what’s going on.
