Hi all

Don't know if anyone can help, this one has me a bit stumped.

Just upgraded my PC (by literally replacing everything barring the hard drives and case). New rig is as follows:

I7 6700k (not overclocked yet)
MSi GTX 1070 Gaming X (running stock speeds)
Gigabyte K3 motherboard
16Gb Ballistix Sprt LT Ram (2 x 8GB)
CX750m PSU
980GB Sandisk Ultra II SSD
2 x Generic 2TB Hard discs
Dell 2515h 1440p Monitor
Generic AOC second monitor not used for gaming (1080p)

Everything seemed to be great at first. Getting great FPS's in Doom (100fps), Dying Light (60fps), and Farcry (80fps), all at 1440p.

However in XCom 2, I am only getting 30-45fps (which I appreciate is a poorly optimised game), and more surprisingly in the Witcher 3 I am also getting 30-45fps). If I dialled down the detail, it makes no difference. In the Witcher 3, I got down as low as 1024 x 768 at low settings and was still averaging 33 fps. (no I did not leave hairworks on :) )

It looks like these games are bottle necking somewhere but I cannot for the life of me work it out.

CPU scores 867 multi core and 171 single core in cinebench r15.0 so dont think I have a duff CPU.

Similarly I dont think its a duff GPU as I get avg 63.8 fps (min 26.7) in the heaven benchmark at 1440p on ultra quality with extreme tessellation, which is in line with reviews I have read online. MSi afterburner does however show the GPU usage does not go above 75%.

I have tried removing each stick of ram (not at the same time) but doent look to be a ram issue.

I have rolled back Nvidia drivers to see if it was a driver issue....nope!

Have transferred the games from the HD to SSD and still no improvement.

I have even unplugged the 1440p monitor to see if there was an issue with a multi monitor set up.



I am at a loss. I am probably missing something very simple but am stumped. Does anyone have any ideas?

Thanks
 
Monitor your CPU/GPU usage, coreclock, temps, etc... More than likely your CPU is either being hogged by another application, or being throttled (possibly by a rogue power saving feature). This doesn't sound GPU related as it works fine in several of your games.

Try using MSI afterburner/riva tuner to monitor your system. Include screenshots if you can.

Thank's for the help.

The Windows setting does say balanced not power saver. I have also swapped out the PSU for my old one (a cheap 500w one that I fear may one day burn down my house) and that did not change anything. It used to be able to power an fx 8320 (overclocked) and GTX 670, however I'm not sure if the power usage is comparable to the current system so 500w may not be enough.

I don't think CPU and GPU temps look anything exciting. I have taken a screen shot though.

CPU usage whilst playing the Witcher 3 in the town. around 45-50% usage.

Settings were 1080p medium and still just 30-35 fps :-(
 


You don't happen to have vsync half rate turned on do you? Just to make sure, have you completely disabled vsync?
