I am new to UE4 and am currently working on a game. The issue is, the main map loads really slowly (it just hangs for about a minute); both in the editor preview and in the packaged version. My computer has a NVIDIA EVGA GeForce GTX 750Ti with an Intel Core i7-4890 @ 4.0Ghz.
How much content is in the map, and how much ram do you have?
There is quite a lot of content, but I have 32GB of DDR4 RAM (My graphics card has 2GB of GDDR5)
That seems to be the issue. I haven’t done any optimisation at all. It runs much better now. Thank you!
if you have a lot of content, high poly, or hi res textures your card may not be able to handle it. I used to have a similar card Asus 750ti and it sometimes had some trouble. Does it load other maps with less content in them faster? You may need to eliminate assets or make optimizations such as LODs. You could always try separating your level into smaller sub levels ans use level streaming to lighten the initial load on your system.Also is it only when loading levels that its slow? if its slow all the time it could also be heavy in the scripts.
