Hello everyone,first time PC builder here, please hear my cry for help.
Here are my specs:
When i freshly boot my PC i get a 3DMark Spy Glass score of 9800 to 10200.
After playing a game or running the benchmark several times with short breaks the score tanks to 7900 and even 5900 .
I also ran the Final Fantasy 15 benchmark and the first minute things run super smooth but at one point it hits some kind of bump and the performance tanks.
One would think it's a bottleneck but considering the parts of my PC there shouldn't be.
I already tried doing a clean install of the GPU driver using the DDU tool aswel as the built in option in the Nvidea installer. Also tried an older driver.
I also checked my power cables, unplugging and replugging them.
I monitered things in MSI Afterburner and noticed the following:
The weird thing is that to get full performance again once i hit that bump i need to reboot my PC.
I then run Spy Glass again and get normal score.
Same for the FF15 benchmark, super smooth the first minute or so and then BOOM, the performance drop.
Some more stats from during last test:
All ideas are greatly appreciated.
As we say in Dutch "I have my hands in my hair!"
EDIT:
I think it has something to do with the power ussage.
I rebooted my PC and ran Spy Glass three times in a row with a 10280ish score.
Then i boot the Final Fantasy 15 benchmark and the first minute it runs super fast/smooth.
After that it runs ok but the drop is noticable.
I check MSI Afterburner and from the moment i noticed the performance drop the Power % goes from 97-100 to about 80-85.
Also the Voltage limit goes to a flatline 1 value instead of bouncing between 0 and 1 like it did the first minute of the FF15 benchmark and also all three of the Spy Glass benchmarks.
I wait 5 minutes and run Spy Glass again and only get a score of 7377... . How is this possible?
During this last test my power % was also limited to 77-85%.
EDIT 2:
So today i booted my PC, opened MSI Afterburner and ran the Spy Glass benchmark first.µ
I got a score of 9950, wich is reasonable but yesterday after bootup i got 10280 three times in a row.
Then i launched the Final Fantasy 15 benchmark and the performance drop happend again.
Please have a look at these screenshots.

So as mentioned before the performance drop goes hand in hand with a drop in Power % and constant Voltage limit of 1 instead of bouncing around like during the Spy Glass test. Temperature did not go higher than 73C.
Is my GPU the problem or my 750W power supply? Again, nothing is overclocked, CPU temps do not go above 65C and CPU usage spikes to 64% max during tests.
Here are my specs:
Asus MAXIMUS X HERO- Motherboard - ATX
Intel Core i7 8700K - Processor
Be quiet! Dark Rock Pro 4 - CPU Cooler
Corsair Vengeance LPX - DDR4 - 2x16GB
INNO3D GeForce GTX 1080 Ti iChiLL X3 Ultra - GPU - Boosts to 1721 MHz
Cooler Master V Series V750 - Power Supply
Samsung 960 EVO 1TB - Solid state drive
WD Black Performance Hard Drive 4TB
3x 140mm be quiet! Silent Wings 3 case fans - 2 in the front and 1 in the back
Monitor: LG 32GK850G-B - 1440p - G-Sync
Windows 10 64bit
1440p G-Sync monitor
Not overclocked

Some more stats from during last test:
Max CPU clock : 4503Mhz
Max CPU temp: 62C
GPU max voltage: 1.063V
Max GPU temp: 64C
Max GPU power %: 83% (often went to 100% during previous tests)
Max GPUGraph clock: 2000Mhz
Max GPU Mem Clock: 5702Mhz
GPU usage: 100% (it runs constantly at 100% during Final Fantasy 15 benchmark)
All ideas are greatly appreciated.
