Best Settings for Nvidia GT 710
I don't want to sound unfounded, but I've heard that older NVidia graphics cards flashed with newer BIOS versions are less comfortable to use. However, I have no evidence to support this.
WhisperingWind newer BIOS versions are less comfortable to use
I got not same but close: gtx1060 with new (rtx30+ era) drivers not calm as with old
Perhabs, devs introduce new code features and force all devices to use it

Oops! Sorry about that, I meant to reply to Dizzy in my previous post, but I must have accidentally clicked on your name instead. 
WhisperingWind I appreciate all this knowledge sharing no matter where placed!
i recommend you to buy a used geforce gt 6 series like gtx 650 ti , gt 610 … it worked to me , zero eye strain
@Dizzy is your card this one: https://www.msi.com/Graphics-Card/GT-710-2GD3-LP/Specification ?
WhisperingWind I can confirm this. If @Dizzy has the "newer" 710 it is using Kepler 2.0 architectures. I purchased many of this type and they are not good. An original Quadro K600 or K420 is better.
Dizzy Yes, according to https://www.techpowerup.com/gpu-specs/msi-gt-710-low-profile-2-gb.b4101, this is using the Kepler 2.0 architecture. Tried many of those, didn't work for my eyes. My suggestion would be to go with Quadro K420. It is using the Kepler architecture and it works best for my eyes (and Windows 7) and is also a low profile card. A Fermi architecture card also is good (Quadro 600 for example), but I found them to heat up a lot and causing fan noise.
Which OS are you using, Windows 10, 11…?
