Good morning, everyone. My rig:

i7 4790
Motherboard: z97M-PLUS Asus
GPU: GTX 1070 - Galax Sniper White EXOC 8GB
RAM: 2x8GB 1866 Mhz Hyper X
HDD: Seagate Barracuda 2TB
SSD: Samsung EVO 850 250GB
PSU: Corsair CS 650M
Mouse: Logitech g502
Keyboard: Corsair Raptor K40
Windows 10 64 bits

I replaced my i5 4690 with i7 4790, but the performance isn't convincing: there are sttuters and the FPS doesn't get stable at all, even in very light games, such as Sky Force Anniversary, Tales of Berseria and Guilty Gear Revelator. For some reason, the FPS drops to 40 and sometimes even 30, then goes back to normal. I already checked the temps, using a TX3 EVO, it's hitting max 70c (I live in the hottest area of Brazil), also I monitored usage % when such thing happens, but I see the values are pretty fair and balanced, nothing extreme going on. Also, I monitored my SSD and HD to see if that was their fault, but nothing.

Any guess on how I could solve it?

Hi

Could you test a few more games and see what FPS you get. Test a mix of CPU and GPU intensive games and see what GPU usage you get ideally you want either frames to your max HZ's or if the game is to demanding for that the GPU should be at 99%.

Some games do need to be installed on a SSD to remove some stutter such as Witcher 3 and BF1 for example.

Though a HDD is totally fine 90% of the time.

What HZ and and resolution are you at. Do you have Vsync & Triple buffering on or off?

Also side note i use to have a 4460 then went to a 4790K and i saw a good boost in CPU performance for Witcher 3 but Bf1 was to demanding, i had to overclock it but it still kinda struggled.

Lets see if we can figure out whats causing this.

I tested with Assassin's Creed Origins at High preset with some things in highest setting and got CPU at 90% and GPU at 70%. That game has a double DRM layer or so, which eats a lot of CPU usage, so I was expecting that. Though the game ran quite ok, with some constant drops, though. It could make 60 FPS, but there was something making them go down. In Ghost Recon Wildlands, I got an average of 70% CPU and 80% GPU, both running around 65c. In that game, the FPS kept a bit steady, despite some expected drops, but not huge ones. I got cars and motorcycles and forced the game, but it could handle 56, sometimes 52 FPS minimum, which was rare. Tried explosions and zooming with a gun, while looking at a car on fire and the results were the same. It's odd how it's doing quite ok there.

One thing I didn't do after changing CPU was formatting the system. Should I resort to it now or is it too early?
