MSI GTX 670 Poor Performance

[striker512]

I bought GTX 670 half a year ago and it performed greatly that month. It was already 3 years old. It performed Assassin's Creed Unity at 60 FPS for a month. Later, poorly. Then I bought Grand Theft Auto 5. For a month it performed 60 FPS and then later poorly. For every game, I've applied nvidia game optimization's "optimized settings". These don't make any game smoother at all, but before it did.

What's wrong? Can it be fixed?

How are your CPU/GPU temps? Maybe something is overheating. What did you change on the PC? Did you install something?

probably driver related or malware on your computer. Do a clean install of all video drivers. The 670 is a old graphics card and with the updates to games and not really any updates to the graphic cards of a older nature it could be just that games have surpassed your gpu's ability.
