I’ve recently started copying UE4 over to my work laptop, so I can work on the game on the go, and because much of my development software is on that laptop rather than my home PC (for work of course).
It’s a decently specced laptop, Samsung 880Z w/ dedicated video card and running above 3ghz, and before anyone assumes it’s the laptop itself it actually runs the pre-built download of UE4 nicely. Problem is, I recently setup a build for the C++ compiled version, setup instructions (the same exact way I did on my home PC), but now when I run the editor it has horrible performance. I mean even with graphic settings turned to low and unlit shaders I get 1 frame every 5 seconds or so. That’s worse performance than the prebuilt editor with max settings in the (small) project I’m testing.
Any idea what could be causing this? I thought it might be the initial compiling, but I left it idle in scene after launching for awhile and it has not shown any improvement. Is there any reason there should be such a drastic difference in performance that I may have missed?
