Huge FPS drop when holding CTRL: any way to tell how much CPU a mod is using?

[Lupin III.]

I usually have around 45 FPS (+-10) in a game, with or without any mods installed. When I hold the CTRL key to get the mouse pointer it drops to around 30 FPS in "clean" WoWs (integrity checked and no mods). If I have mods installed and hold the key but don't move the mouse, it drops to about 15FPS. As soon as I move the pointer it drops to 5 FPS and if there's a few planes my game turns into a 1 FPS slideshow, making it pretty much impossible to select any plane or other ship for secondary fire/AA.

Is there a way to find out which of the mods is causing this hogging of CPU as soon as I move the cursor? The method of activating/deactivating single mods and trying it out doesn't work well, because I pretty much need to play full games to be able to tell if it did really change anything and do that for a quite a few combinations of mods.

 

Currently I have these mods installed (text from the current 0.6.4.1 _Aslains_Installer_CompList.log file):
