Sounds simple, but the tried and tested method of turning it off and back on again can sometimes be the easiest fix. It's possible you're running into memory problems and just need to clean house.
Update graphics drivers
Out of date graphics drivers can cause a variety of performance issues. If you have not updated your graphics drivers within the last 6 months then they may be out of date.
Clear your cache
Make sure the installation of the game is up-to-date and any bad or corrupted game data is repaired by clearing your cache.
Run a virus scan
If you run RuneScape or Old School while infected with a virus, this could cause significant performance issues. Download and install your preferred protection and scanning tools.
Try a different user account
New Windows user accounts usually have the default Windows settings and programs, so creating a new user profile can highlight where incompatible programs or settings are causing problems.
If you have tried the above and you're still experiencing crashes, then please get in touch.
