I can still open the original project I referenced that was done in Windows with all Windows plugins, and it plays OK if I increase my audio buffer to 512 samples. Normally I run my machine at 128 samples.

With 94 FX on 25 tracks including Superior Drummer and a lot of Kontakt instruments the difference I'm seeing before and after swapping out most of the FX to native Linux replacements was this.

Playing the original file with 94 mostly Windows FX = 54.36% CPU use.
Playing the modified file with 94 mostly Linux FX = 30.59% CPU use.

Takeaway result is you could leave projects as is with Windows FX, and unless there are a ton of them, probably be fine, but there will be higher CPU use running Windows plugins in WINE bridging them with LinVST vs using native Linux plugins.
