If it doesn't help your problem, then try this;
.1  - Clean the RAM before starting Gunz.
.2 - Try to use the Disk Defragmenter.
.3 - Gamebooster can also help.
.4 - Decrease the resolution in game.
.5 - Disable Full-Screen Optimizations in the Launcher proprieties (Windows 10).
.6 - Disable Visual Themes and Disable Desktop Compositions in the Launcher proprieties(Windows 7).

Please try these two options and let us know if it helps!
Thank you!
