thanks for your replies :3 Today before playing I once again re-installed the drivers and this time made sure it was a clean re-install. Turned the GPU performance up and, as last, ran cmd.exe to diagnose and repair corrupted files on computer. Restarded the whole thing. I also put my game in borderless windowed mode and fps limit to 30

And it worked. I only got lag and stutter once, on Ifrith EX. Apart from that my game behaved very smoothly to the point I even got bit bold and upped some of the graphics settings like turn on the grass and smoother shadows and anti-aliasing. I am not sure which one of these things did it but for now it works. i shall see how it goes tomorrow.
