1080ti - i7-6700k - 50-150fps heavy input lag, help?

[Robbowz]

Just upgraded to a 1080ti, and somehow i went from steady 280-360fps with my old 960gtx to 50-150 with 1080ti. And with a 144hz screen, it's horrible. Also the input lag (feels like the mouse is being controlled on remote control, that's how slow the mouse movement can be sometimes.)

 

I've tried to boost my settings high, low, big/small/medium resolution combos to boost the effect from the card. Windows power settings are set to maximum perfomance, settings in nvidia are set to maximum performance, tried various settings in nvidia to give more "load" to the graphic card, did not help. Tried turning off Hyperthreading, turned off parked cores (C States) and so on in BIOS, disabled iGPU, tried XMP and simple EZTune OC (about 10-13% OC). Reinstalled drivers. Reinstalled Windows. Made sure game is on SSD. Updated all chipset drivers (Thanks to Driver Booster for the easy driver findings). Bought new motherboard.

 

I will try to take the graphic card out and try it in another PC if i get hold of some friends to help me test it.

But it will perform if i use it to mine coins or other stuff, so i know the PSU can deliver the power and windows can deliver so shouldn't be anything there throttling it. And also the i7-6700k should not throttle it either.

 

My theory so far is that, the graphic card "doesn't wake up" while gaming CSGO so it gives 99% of the job to the processor, giving it heavy input lag. Reason for this theory is basically: GPU Load: 0-9% during gaming CSGO PerfCap Reason: Idle (From googling this means the same as Util) Power Consumption: 25-29% TDP (Does not exceed this point while gaming) Barely anything else changes either. All those mentioned readings from GPU-Z does change to a high value (100% load, 100++% TDP and so on if i turn on mining)

 

Been googling and testing this solution for days, even bought more fans and a new cabinet, and as mentioned new motherboard. Currently rocking Asus Z270E - 1080ti Rog Strix - Be Quiet Dark Base Pro 900 - Intel i7-6700k - 2x 8gb 2666mhz hyperx fury - MX300 SSD, masterwatt lite 700watt PSU (more than enough power for the system).

 

Also tried various console settings, mat_queue_mode (all of them) fps_max 0, r_dynamic 1/0, snd_mixahead 0.5/0.25, on/off 3d sound (HRTF), probably some more but minor impacts on any of the commands i've tried, and most of the commands i have is mostly related to connection (internet) or preferences (viewmodel etc).

 

Also the graphic card is in the correct spot: PCI-E Slot 1 x16 Memory is installed to the correct slots, A2 and B2. CPU Cables are fitted properly, EATX Cable is fitted properly, Power cables for PCI-E is fitted properly.

 

TL;DR
Upgraded to 1080ti, low fps, high CPU usage, barely no load/tdp on graphic card.
I've swapped:
Motherboard
RAM
PSU
Cabinet
CPU Cooler

Checked settings like:
C states
Hyperthreading
Overclocking
XMP profile
Disable/Enable iGPU
Nvidia settings, max performance (global settings)
High/Low game settings
Vsync is off
Windows settings, max performance
No XBOX activated
GeForce Experience not installed
Shadowplay not installed
CAM not installed

Basically, csgo will not cause any load or TDP changes to my graphic card, so it's just idling and not using any resources whatsoever. While other games/tasks will activate my graphic card with no problems.

@Robbowz I have very similar issues with all my games regarding input lag using an EVGA 1080ti FTW3 and an Asus IX hero board. I've tested on two separate computers using that 1080 ti with identical problems. I don't necessarily get low FPS like you do but I get input lag that comes and goes even in offline games. I'm currently running some tests on an r9 390 setup so I can determine if its for sure an GPU relates issue or not. So like you I've replaced every part in my computer with no idea of what's wrong.

 

In any case I'm going to be running input lag tests with both setups over this week with Far Cry 5 to see if there's any difference.
