Refresh Rate Problem

[Cube_of_Rubik]

Monitor: Asus VG248QE (using DVI adapter)
Processor: Intel Core i3-4350
Graphics Card: Asus GeForce GTX 750 Ti 2GB
Memory: 8GB
Power Supply: Corsair CX430M

I found out that the reason my computer crashes when I play Overwatch is because the temperature gets really high (around 70C) when I'm playing on 144 FPS. So I turned the refresh rate of the monitor to 60hz via Display Adapter Settings > Monitor > Monitor Settings > Screen Refresh Rate. I used Nvidia Control Panel as well to change it to 60hz. Also, I changed the settings in Overwatch to handle 60 FPS only. However, I noticed that the screen gets really laggy. The mouse isn't smooth when it moves. The Windows animations get really laggy too. I see tears on the screen when I play Overwatch. You might say I'm just so used to the smoothness of 144hz, but I know that 60hz is so much smoother than what I'm experiencing now. How do I solve this?

The issue here is that Overwatch uses Vsync to limit your framerate to 60 fps - and vsync always introduces input lag.

In most cases, you can avoid this issue by "software limiting" your FPS instead of through vsync. MSI Afterburner has an option to limit FPS - use this instead, and disable framerate limit within Overwatch.

Also, you don't have to limit your monitor framerate - leave it at 144 Hz. Leave it at default even in Nvidia control panel. MSI afterburner should make sure that you don't see more than 60, and that your GPU does not work harder than in needs to.
