Is there any performance difference between using GPTK-latest and Crossover 24 + D3DMetal?

I'm getting BakkesMod to work on Rocket League, but it has issues injecting itself when I run the game via GPTK, and it seems to be fine with Crossover 24. Now that Crossover has GPTK built directly into it, is there any actual difference between selecting GPTK in the Rocket League Heroic settings over Crossover 24?
