Live coding compile so slow

[Jonathan_Ferrer]

Hello, I have a problem with live coding. It’s frustrating because everything I do takes at least 1 minute to compile, even if it’s just creating a new class or adding a “;”. I’ve seen other people not have this issue. I stopped the course a while ago because of this problem and can’t find a solution. I have an AMD Ryzen 5 5600 6-Core Processor and 16.0 GB of RAM. Unreal Engine and Visual Studio are on an SSD, so I don’t think it’s my hardware. Please help me.

Hi Jonathan,
It could easily be your hardware. I would normally recommend at least 32GB min on ram (I’m upgrading to 128GB first opportunity I can) and the equivalent of a 10th Gen or later i7 - cores count when compiling C++ and the more ram the more cores it can use effectively. Your CPU seems to be on a par with 11th/12th Gen i5 CPUs which is a little on the light side.

So, generally, the specs for UE 5.x are an i7 10th Gen or later or AMD equivalent CPU, a minimum of 32GB ram, a high end 10 series or 20 series NVidia with RTX if you want to use raytracing (realistically you want a 4080 or better for that) and 2x SSDs, where youhave OS on one, and Engines and projects on the other. (I use 3, where one for OS, One for engines, one for projects)
Also, Laptops are not ideal but can be used at a pinch unless you spend real money (like my office laptop is about 5k and has an RTX GPU in it and I don’t even work with UE there)

Just to be clear, your projects should be on the SSD, not any other kind of drive (external SSD doesn’t count). Also, it shouldn’t be in the documents folder or anywhere where a cloud drive backs up (OneDrive as an example backs up Documents and Desktop for starters) so it is best to create a folder in the root of your C Drive called development or something ad put projects in there. Lastly, exclude the entire folder from your virus checker as this can affect performance.

If you’re still having issues, RAM will probably be a cause and VS 2022 is quite heavy. Rider is now free for personal use so is worth trying that instead. It’s a lot lighter so doesn’t require as much free Memory (VS will happily use 8-10GB of RAM when running)
