I was wondering why PopcornFX editor is worse on a PC with i7-2600k 3.4 GHz processor, GeForce GTX 1060 6GB GPU, 16GB RAM than on a laptop with i7 3610QM 2.3 GHz processor, GeForce GT 630M 2GB GPU, 8GB RAM. Both are running Windows 10.

Thank you for your time.

Can't be sure why it behaves like this without more information. First thing that jumps to mind is the CPU: the i7-2600k has the older sandy-bridge microarchitecture, while the mobile i7 3610QM has the ivy-brige uarch, but they're largely similar, so it probably doesn't change anything.

A couple questions:

Q#1 : Are you looking at the framerate displayed in the viewport to tell it performs worse ? something else ?
Q#2 : Does it do this even for empty effects ? if yes, what kind of framerate values are you getting for an empty effect ?
Q#3 : can you take a screeshot of the profiler (ideally on both machines), in a situation that performs worse, and send it over to us on support _at_ popcornfx _dot_ com ? To show the profiler, see button #4 on the bottom viewport toolbar.
Q#4 : can you try disabling all post-effects in the viewport and compare the framerates again: does it change the perf balance between the two machines ? to toggle post-effects, see button #12 on the top viewport toolbar
Q#5 : is PopcornFX the only 3D application that exhibits this behavior ?

Thanks !

1. I'm looking at the framerate displayed and it's quite noticable because the editor starts to lag (every click takes some time to get registered)
2. No.
3 and 4. I just started learning it so I don't know how to make things. I'm learning from the examples. To "test" this I loaded the "LOD" example and turned the "Detail" up to 100 to see how it looks, what it does and how it's made. On the laptop the FPS goes from around 125 to 65 and on the PC from 125 to 15. Same settings, same camera position.
5. As far as I know, yes.
