Game Has terrible Lag and CPU crashes!

I have been playing with little to no Latency or FPS issues after getting my new Graphics Card last year, recently I upgraded to the new Directx and drivers for the Card and everything seemed a little better. Then this week I go to try to join and play through my first game of Comp overwatch. The game seems to have latency issues every minute or so I will be stuck on a frozen image on the screen while the sound keeps going I can interact with the game I was in until it caught up.
The next map wast much better but then the game crashed, and i ran the game repair and the same thing happened again.
Is this because of the Extreme usage of the servers since its opening day for the new comp season? Because like I said there wasn’t issue before?

You might want to run through these steps first:

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 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.

Also here are advanced tips I have written in Overwatch’s Tech Support forum that maximize your FPS performance in the game.
