Question GTX 1080ti FE Underperforming

Nov 3, 2019
Hi guys,

I've this issue for about 10 months but I fail to figure out what is happening:

The machine is:

GTX 1080Ti FE

I7 4790k

DDR3 Hyperx 16 GB (2x8)

Asus z97-c

GPU and CPU both are custom water cooled.

Monitor - 2560x1080 LG (Monitor is freesync, but I am not using it anyways)

Remarks (as I got this offered as a solution quite often)

- Temps are OK - not more than 40 degree C

- GPU is running at 3.0 x16

- Tested with different DDR3 RAM - no change

- Tested both overclocked and stock

- Tried in different GPU PCI slot and different I/O port with both HDMI and DP)

Now the issue: In my opinion the GPU is quite underperforming since in GTA V i get around 60-70 FPS max with many things turned off. Even when i lower some of the settings i barely get around 90 FPS. The intersting part is that on FireStrike and Heaven (not sure was called that) I get around normal results. Check FireStrike: https://www.3dmark.com/3dm/40675738?

On Dota 2 I also get around 100 FPS which is also not normal.

Yes, I reinstalled all drivers, even reinstalled windows 10. Another interesting thing is, no matter if I run GTA V and dota on 1920x1080 or even the the Nvidia Super Resolution 3xxx x 15xx (something like that) i get no change in FPS

I have no clue what is going on....

Thanks guys :)
