Hi all in case you still wondering I did a research in the new spanish pes6 community (
www.pes6.es ) and the current problem, AFIK is held by 2 things:
1. using internal GPU in laptops and motherboards with GPU of some kind.
2. Dx8 mal-use in W7/W8/W10 ( Think internally is due to some kind of emulation I remember I have read this in Dx forums) Sometimes installing old Dx helps to have it explicitly avialable not emulated in the system,
The important part is that we have the files in pes6.es its indeed related to this (See attachment)

And also you have now 2 methods of knowing and using the propper GPU, one is checking it in the task manager (W10, see if GPU is 1 instead of 0 ) when pes6 is running you can see the details in the taskmanager/processes.
and then nVidia control panel for explicitly search the exe file, add and apply high performance GPU.
Also in display settings Windows control panel / display / performance has now an option similar to the one for nVidia to do this but for me was not working.
Like I always said, trust me there is a solution for this game and its stuttering.
Also play with Kload to set the
dx.force-SW-TnL
dx.emulate-HW-TnL
to 1, sometimes help with low graphic cards. Play with these options of your PC is low and OFC lower your graph settings in the pes6 settings exe.
