Try to do following things in order to make your PES 2017 run more faster:
-If you have an Nivida card - try going to the NVIDIA control panel. Go to the program settings for Pes 2017 and set "Preferred refresh rate" to "Application-Controlled", and "Vertical Sync" to "Adaptive".
-Switching from Fullscreen to windowed mode will also help
- Download latest Ati drivers and set options to medium,and now it works fine.
- make sure nvidia backend is disabled, before running the game.
Fix for online LAG/problems:
Just enter in your router configuration and turn off NAT Filtering (should be open).
