Unreal 4 memory requirement for a early 2008 mac model

I have a mac early 2008 with 4gb SDRAM and it runs terribly if I upgrade to 8gb would it make it run smoothly or mac it run terrible whats your recomendation?

On Windows PC it would help out, but on OS X i don’t know, it depends on how virtual memory works as it’s main source of slow down in case of low memory. As i know newest OSX do memory compression which would be better in that case. 2008 is very, so i would not be too optimistic on performance boost with just memory upgrade.

Ultronsu17 the problem is likely not just the lack of memory, but the relatively slow GPU your Mac will have. Our recommended spec is an NVIDIA GeForce 470 GTX or AMD Radeon 6870 HD series card or higher. At an absolute minimum we require an Intel HD 4000 or an Nvidia 640 or an AMD 5750 or better in order to render correctly on OS X.
