It’s believed to be the lush or very lush outfield. Looks great but is slow. I changed all mine back to standard and re shared so re download if you want.
Don't think its just the lush outfield. I tried a few before ,none of which had lush and it was still slow. Someone here on another thread suggested to reduce pitch friction setting inside the stadium settings. Tried that on one stadium so far and it coincided with a much better experience, both for me batting as with good timing was able to hit boundaries, unlike before ,as well as AI, which used to really struggle esp against spin. So maybe that might help too. Still yet to test out other grounds
