Random blackouts in games

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag.

Random blackouts in games

Code: Select all
Acer Predator G9-593
Intel Core i7-6700HQ (2.6Ghz/3.5Ghz) (https://goo.gl/dehk14)
Nvidia GeForce GTX 1070 (8Gb GDDR5) (https://goo.gl/z2aEFL)
15.6inch 1920x1080 (G-Sync) (IPS)
16Gb DDR4-2400 / PC4-19200 (2x ACR24D4S7S8MB-8)
Windows 10 x64
Nvidia driver - 378.49


So, sometimes, extremely rare, while i'm playing i'm getting these blackouts. Screen will just go black and then will turn on again. Happens faster then a second. I was playing Resident Evil 7 today and it happened once. Earlyer i was playing Ghost Recon Closed Beta and and happened when i was using my drone.

So its totally random and rare, but still i worry.

And additional issue, dunno if it somehow connected:

I’m using msi afterburner to overclock my gpu and assigned 2 keys for switching overlock profiles, default and overclocked.

And when g-sync is enabled I’m getting quick blackout when I switch profile. Nothing like this when g-sync if off. Take a look: https://youtu.be/kg_0kXi4U88

Made some further testing. Launched quake II and tried same thing with g-sync ON, nothing happened. Then i've lowered fps to 5 and switched OC profile once again, and this time i got same blackout thing.

I also have a 1080p G-Sync and I get that once or twice a day ingame or out, i'm pretty sure it's only recent but it doesn't really bother me.

Even in Windows? Hmm.

Finally captured some real gameplay. Happens from time to time in Dishonored 2 while game is around 30 FPS:

Okay, finally, after 4 month with this laptop i solved this issue.

Cleaned everything via DDU and installed latest 381.65. No more blinks, even on clock switch.
