[Solved]Really bad performance with 1080 Ti Aorus Xtreme

[BlackDragon]

Hi,

I've had my Aorus Xtreme for a while now, but it is performing terribly.

I've noticed in most games I am getting frequent and noticeable FPS drops. I've noticed the drops on Battlefield 1, Overwatch, and Ryse: Son of Rome. On Overwatch, the FPS tends to stay around 80 FPS, and dropping down to 40-50FPS in a fight, although I'm sure it is getting lower at some points because it's like playing in a slideshow. Witcher 3 I get 20-30FPS. This is worse than the 1070 I had before!

I've tried uninstalling drivers with DDU, then reinstalling the nvidia drivers. Also updated my motherboard firmware to the latest.

I'm playing at 2560x1440 with a 144Hz monitor, with the following specs:

• i7-6700K @ 4Ghz
• Gigabyte GA-Z170X-Designare
• Corsair Vengeance 16GB DDR4
• EVGA SuperNova G2 750W PSU

I'm completely at a loss as to where the problem is, and would really appreciate some help!

Here are some graphs of my system which may or may not be useful. The only thing that sticks out to be is the GPU usage isn't maxed out. I saw the same stats through the Aorus monitoring utility.
This is during Overwatch:

This is Witcher 3:

Here are some more graphs that shows GPU load being quite low and erratic while playing various games.

BF1:

Overwatch:

3D Mark Time Spy is the only exception:

I'm sure I've read something about issues with the software/fan profiles? Maybe worth checking out?

I'll have a look in to it thanks.

I'll look in to swapping in a 970 tomorrow, and try out the 1080 Ti in a different machine if possible.

Are you using Windows 10? did it update to the creators update between those 2 GPUs if so?

Yeah I'm using Windows 10. I switched from my 1070 to a R9 290 in March, so I will have had all the Windows updates in between then and now. I do seem to have the Creators Update as I can bring up the game bar and enable game mode, which makes no difference.

Finally found the issue, which is a little embarrassing! Turns out my memory was not in dual channel configuration. I must have misinterpreted the manual and put them in the wrong slots. As soon as I corrected this, the benchmark tests I've run have improved significantly.

Somehow this didn't have a noticeable affect since building this machine in November, until I upgraded to a 1080 Ti recently, where I suppose the bottleneck shifts away from my graphics card in some situations.

Thanks for your suggestions. I've gone through them all anyway

Unfortunately, despite what I had posted previously, the problem was not resolved

The RAM not being in dual-channel configuration did cause an issue with the CPU benchmarks (e.g. Cinebench), but didn't improve my gaming performance. GPU usage was not anywhere near maximum, CPU usage was generally high, but FPS was generally than expected and would keep dropping significantly or stuttering

For example in Overwatch, my FPS was around 80-100, and constantly dropping to 20-40 or stuttering, which made for an unplayable experience. Dropping from Ultra settings to High had absolutely no impact.

I couldn't figure it out, so decided to just reinstall Windows 10. Somehow this has resolved whatever issue I had. To be sure, I fired up Overwatch on Ultra, and my FPS did not dip below 144 for the whole game!

Very pleased that I have resolved this issue now

Thanks for your suggestion Itron, but I've had those settings turned off from the first time I installed. So for me the performance issues weren't down to that.

I came across another forum post that Gigabyte EasyTuner could have caused issues with CPU usage. I wasn't using it but I think the AppCenter tried to install it in an update. Unfortunately I can't test whether it was the cause now that I've completely reinstalled.
