8 Gigabytes of RAM is actually pretty slim (though it exceeds the Recommended System Requirements for Overwatch) and can hinder your performance at higher settings. I recommend keeping it no higher than “High” for your general render performance settings unless you can replace your RAM to a higher capacity.
Again the RAM can have some impact on this. However I would be curious to know if you use a Hard Disk Magentic Drive for your harddrive or if it is a Solid State Drive. A lot of frame rate issues can also be affected here.
Aside from that, these standard tips can help resolve most Overwatch FPS drops:
- Reset Overwatch’s Video Settings
- Update your graphic card driver.
- Reset your graphic card driver settings., then make sure that your Graphic Card Driver control panel is configured correctly for Overwatch. This includes setting Overwatch at Maximum Performance (not optimal power) for Power Management and making sure it set to run on the graphics card and not the motherboard chipset.
- In drastic cases you may need to reinstall the driver and update to the most recent driver for your card. Remember to use Display Driver Uninstaller to completely clean out your old driver. Then download the most recent NVidia or AMD driver for your system.
- There have been other threads reporting that updating your system BIOS can help with some performance issues with recent patches. Please be careful if you choose to update your BIOS and look up your motherboard’s instructions on how to do this.
