I do not get crashes anymore, i did a complete reinstall of FF7 and still got crashes.
From there i tried out a few options in the config, posting this just in case someone has a similar problem to me, with random crashes which can occur at any moment.
User Options-Make your screen resolution the same as your desktop (1280x1024 for me)
-Preserve Aspect and Full Screen = Yes
-V Sync, Minigame framelimiter and Battleswirl framelimiter = Yes/On
-Linear Filter = Off
Enhancements-Transparent dialogs = Off
-Break damage limit, Mdef fix and new battle interface are your choice, Yes/On for me
-Enable Postprocessing = No*
Advanced-Use Shaders= Yes
-Prevent rounding errors = Yes
-Fancy Transparency = Off*
-Compress Textures = Yes
-Use new timer and stable timer = Yes*
*These options should definitely be this way, after finding this combination i no longer get crashes!
