Dropping to 30fps randomly in games

[Darkrachet]

I just got a new machine, and after 30seconds of playing a game my fps drops from 60 to 30 and below and will stay there until I tab out. I've tried downloading different graphic drivers and changing the speed of the fan on msi afterburner with no success.

In this thread http://www.tomshardware.com/answers/id-2196933/maxed-gpu-usage.html I followed the mods advice and turned on adaptive vsync, and I thought I had fixed my problem, but after further testing the problem still persists.

Here are the specs:
OPERATING SYSTEM:
Windows 2.6.1.7601 (Service Pack 1)

What game?

What detail settings?

The 750 Ti is a mid range card, so many games it wont be able to sustain 60fps at all parts, so this fps drop may be normal.

Ok I put in my old gpu (nvidia gts 450) and the problem is resolved. So sounds like the new gpu is defective.

Either that or the new one is not powerful enough. Try getting something like the R9 280 http://www.newegg.com/Product/Product.aspx?Item=N82E16814202099&cm_re=280-_-14-202-099-_-Product

nvidia gts 750 Ti is much more powerful that the gtx 450 right?

The GTX 750 Ti is much more powerful, but that's not to say that the GTS 450 can't run Battlefield 4 at low settings playable.

I had similar problem in October 2016 randomly started with Windows 10 and after latest GPU driver update. Installed older August 2016 drivers selecting a clean install and am back to FULL speed!
