Sorry for my late reply, but for some reason I wasn't notified about your post in this thread.
PES 4 will always stop running if you have a kitserver installed and also if you restart your PC. Don't know why, but if you restart your PC, or even after a normal shut down that "not responding" clicking on the pes4.exe icon mostly happens. So, when you'll do a restart on your PC you should keep in mind to go where the PES 4 kitserver folder is located, then click on the setup and deactivate then activate the kitserver again. That should resolve this issue...
Now for the stuttering problem I used more than 60 patches on my PC for all PES 3,4,5 and the majority on PES 6. All games are stuttering in Windows 10 or 11 if I don't do the following:
1) Have a fresh installation of your favorite patch (mostly via
@Sany023 installer)
2) Copy the dgvoodoo2 wrapper files posted by
@Ciais and make those specified changes in Dgvoodoo2.conf (after saving that config file you'll want eventually to pack those wrapper files again into an archive to paste it directly in the directory of future patches that you'll enjoy)
3) Go to settings and use a
1024p or 1080p resolution and
high quality graphical setting (don't pick the best resolution there)
4) Go to the Kitserver then change manually the resolution in
Kload.cfg to your native screen resolution (if you have for example 1440p you could pick it)
5) Go to the
speeder.cfg and change the value from 0.97 to 1 (besides the normal stuttering the game could extra stutter from time to time if it's below 1)
6) Go to the
setup in kitserver, then click on deactivate and then again to activate the kitserver
7) On some PC configurations you'll need to
right click on PES6, go to
properties and activate the
compatibility mode for Windows XP Service Pack 2, plus tick the
disable full screen optimization box (but in my case It wasn't needed to do this last step, not even to run the game as administrator).
This process should totally work to feel a smooth experience on all PC PES editions between PES 3 and PES 6 patches...
Enjoy those masterpieces !!!
