CPU performance on newer Intel, W/ e-cores

[Whitling2k]

Now then!  I appreciate this is an old game, but I occasionally pick it up and play a few Tormented Space maps.

I recently upgraded my PC from an Intel i7 6700K (4+4 core), to an i5 14500 (6+6 performance and 8 efficient cores).  Same everything else (GTX 1080, 16GB DDR4, SSD etc).

I had no bother running CW3 on my old CPU, with some crazy large and busy maps with 100s of units.  On my newer CPU, my framerate starts to drop after something like 100 units. 

Any advice?

Apologies for the slow response - we're all preoccupied with the release of the next game: CW-IXE

Bear in mind that CW3 essentially uses a single core. I'm not sure how your processor decide whether to allocate an E- or P-core to an application. I'm not sure if your processor is not thermally throttled. There could be any number of issues.

Do you have any benchmark data that says there is not an intrinsic performance issue with your machine after the upgrade?
