What PC part to upgrade to get faster saving and loading in editor?
Should the engine or project or both files be on the ssd?
Loading and saving are usually bottlenecked by your storage drive. Open task manager and watch your hardware ramp up as you load things in editor. Is anything at 100%? If so, you should consider upgrading whatever part is maxed out.
The quick and easy answer though is that you should probably buy an SSD if you don’t already have one. If you search for a Kingston SSD on Amazon, you’ll find a 240gb drive for under 40 US dollars. Best bang for the buck. With a decent brand.
What’s most important is that your computer boots from the SSD. You will also see improvements if the info you need to load is on the SSD. So both. Sorry, I didn’t see the repy here in my notifications until now. I’m happy to help with any advice you may want about ue4, programming, or computer science in general.
