Hello everyone,
 
win10 1607 / 1709
1000W Corsair PSU
i5 6600K @4.6GHz
16GB DDR4 2133MHz
EVGA GTX 1080 Ti Black GPU driver 378.92, 385.69, 388.13
Asus Z170 Pro Gaming (last BIOS)
144Hz BenQ XL2411T pluged in with DVI cable
 
I just upgraded from a GTX 680 (+win10 1607 and latest 388.13 drivers) to win10 1709 and latest 388.13 drivers (full system format) and an EVGA GTX 1080 Ti Black 5 days ago and i am battleing since then to make it run anything. I have terrible framerate so far, much lower than my previous GTX 680 and even on old games, with also massive stutter.
 
What i tried so far one by one with the 1080 Ti :
- Reinstaled different win10 versions many times with full system wipe every time.
- Reverted back to 1607 win10
- win10 1709 (Fall Creator Update)
- 378.92 driver
- 385.69 driver
- 388.13 driver (this one give MASSIVE stutter EVERY seconds in bonus, absolutly unplayable).
- Enable debug mode in Nvidia drivers.
- Checked GPU, CPU, RAM usage, temp and power usage. Checked PCIe speed.
- Max power plan in nvidia drivers and max performance mod.
- Disabled globaly almost all effect sin nvidia control panel.
- disabled DVR and gaming mode win10
- disabled full screen optimisation win10
- installed all the latest VCREDIST packages for win10.
- tried the max perf energy saving win10 trick (cpu throttling)
- tried disabling as many win10 services as possible.
- disabled all the energy saving of CPU in BIOS.
- tested the memory clear standby list fix.
- updated Intel Driver IEM to latest 11.7.0.1045.
- tried on another PCIe 16x 3.0.
- Tried with different power cables.
- disabled all OC of CPU.
- Tried back with my GTX 680 not changing GPU driver or OS version. I get more stable FPS with my GTX 680 on most of my games (especialy dx9 games, csgo quakelive etc), except a few ones like on Killing Floor 2 (DX11) i get just a little bit more than the 680 (which is supposedly 3x slower at least).
 
Benchmark results (1080p) :
- QuakeLive (which even an integrated iGPU can run at stable 125FPS) : 60-250 fps. (was perfect stable 250 with GTX 680).
- Counter-Strike: Global Offensive : 140-250. (was stable 300 with GTX 680).
- Left 4 Dead 2 : 140 - 250 (was stable 300 with GTX 680).
- Unigine Valley, Extreme HD preset : 137 fps, score 5767.
- Unigine Superposition, 1080p MEDIUM preset : 162 fps, 21770 score.
 
I am desperate right now.
 
e: added some stuff i tried.

Hello again. Thanks for the ideas. I will disable all OC from motherboard BIOS (will save OC profile before, thanks for the idea).
- updated Intel Driver IEM to latest 11.7.0.1045.
- tried on another PCIe 16x 3.0.
- Tried with different power cables.
- Tried back with my GTX 680 not changing GPU driver or OS version. I get more FPS with my GTX 680 on most of my games, except a few ones like on Killing Floor 2 (DX11) i get just a little bit more than the 680 (which is supposedly 3x slower at least).
 
What seems wierd is that my GPU seems to work perfectly when it comes to benchmarking in UNIGINE Valley and Superposition as i compared results with others just to be sure. The GPU in this case seems to deliver its real power.
 
Also i already monitored every possible things and everything seems normal (using GPUz and Afterburner), memory and GPU clocks speed etc are normal in Quake and CSGO. But the GPU load shows it is 20% for CSGO, not even 10% for QuakeLive, the power % is also extremly low. None of my CPUs are bottlenecking btw.
 
Also i already tried 378.92 with both 1607 and 1709 win10 versions (full system format every time) but same result. Should i try even older drivers? I am sleep depraved since 3 days trying to fix this non stop, i'll try some more and then ask for a refund i think.

Kboost will cause the gpu usage % to show 0% when enabled. It's always been like that.

Alright thanks all for your kind input and help. My conclusion, Directx 9 games like QuakeLive and CSGO etc does not seems to benefit from more GPU power, as the engine/driver/directx/etc doesnt seems to be well made. But the GPU does give a massive FPS boost in some very new games like Doom 2016 which runs at 200 fps, is indeed more than 3x what i had with my GTX 680. It's just  shame the fps boost does not work with older games, i think its purely for marketing that they decided to to that (nvidia). Thats the conclusion i came to, maybe i am wrong? The input feel less responsive. Tho i learned a bit while stuffing around to fix the massive stutter i had with GPU driver 388.13.
 
I had tried again A LOT of stuff again :
- I have read that Windows 10 does not run directx 9 games natively but instead emulate it through dx10 or dx11 dx12 and in the process giving lower perfs in dx9 games. Not sure if that's even true. So i instaled directx 9 jun 2010 last release. It changed nothing.
- I tried prerendered frames 1.
- Tried with another mouse with a different brand/software (g403 vs Zowie FK2A).
- I checked mouse pooling rate and mouse tracking quality.
- and a lot of other stuff...
 
 
MY SOLUTION : i use latest Windows 10 build 1709 16299.19 (type winver in search bar and see your version) and the driver provided by Windows (16/09/2017 385.69). I had Windows 1607 instaled with 378.92 and i had massive hard pagefault errors, I made all the updates to win10 1709 and it instaled automaticaly the latest WHQL nvidia driver driver from Windows update. Works perfectly now. I also updated all the hardware manualy with the win10 device manager.
 
I hope this thread will help some others.
I had some wierd artefacts and crashs to desktop in Starcraft 2, Crysis and FurMark (without any OC) and other games. I hope the card is not buged. I will try to bench it now with 1709 and 385.92 and will report back (probably everything will be ok and it will be my last feedback).
 
 
PS : here is GPU-Z screenshot after a Diablo 3 session :

Hello.
 
Quick question, I have just set memory to +1000MHz (max i can set on Afterburner) and ran UNIGINE Superposition on 1080p extreme and it ran with no problems (score 6384), is it safe to try higher? Is it safe to keep it that way? I saw some review website OCing the memory to 400 some 500 some 550 some 750 (all on air cooling ofc).
 
I find it wierd that my GPU won't work at +90MHz so i set it to +75 because i don't want to search the max it can go for i just want a confortable small OC.
 
So for a comfortable small OC is it safe to keep my mem at +1000? Do i have super good memory and super bad GPU somehow or ?
 
Cheers.

:0 dang 1000 memory clock boost in MSI afterburner sounds pretty good that's pretty much 13000 effective if you are stable at that you have golden memory. There is a sweet spot on memory where I find high speed doesn't help and can lower my scores but mine is no where near that on the memory. Some of my games seem to be much harder on my overclocks then bench marks.
