Oh God, sad to hear that! :O
I wish for you to recover soon and build that incredible PC asap!

Thanks, I'm sure all will be well soon. I am, after all, the luckiest man in the world.

Holy shit... now it's happening on the browser.. right here at GOG. Whenever I scroll up and down the line appears and the two halves get out of sync.

WTF is going on? I guess that rules out the Fallout 4 update the other day then.

Maybe your video card is dying.

*edit* After reading your thread, I fired up FO4 last night and it worked fine - actually better than the last time I played it: no stuttering this time and I played for a couple hours. And I also have about 80 mods installed too.

Guess something has globally disabled the VSync on your system. As to what that is, if you said you've already done a full (clean) reinstall/upgrade of your graphics drivers, I can only speculate.

You mentioned you have 2 Nvidia TitanXp GPU's - does that mean you're running them in SLI? (It's a long shot, but worth asking)

Maybe... but as I said... I played it every day the past couple of weeks and then this showed up immediately after an OS update (and as it turns out an F4 update on the same day). If I'm asked to believe in the coincidence of my card dying on the exact same day as updates occurred or that the update(s) had something to do with it, I'm afraid it's a no brainer for me.. in my mind it's the updates. Most especially since, again as I stated, I've had lots and lots of problems previously whenever Win10 updates. But I do concede it is possible it's hardware and a coincidence. I'm just more convinced (at this point) that it's update related.
The 2 Nvidia TitanXp's are still sitting in their original boxes. As is the i7-8700k CPU. And the memory. And the motherboard. And the hard drives/SSD's. lol. I have the parts for that but haven't put it together yet. This is a laptop I've been using for two years now.

Aha, ok, got it! We may be on to something here. I'll switch to computer doctor mode and ask you a couple of questions if you don't mind:
1) What CPU does the laptop have?
2) Does it have integrated graphics?
3) What dedicated graphics card does the laptop have?

Get yourself feeling better and get that new rig built! :P

I don't know if it's just a coincidence, but the tearing hasn't occurred on the browser since switching back to 75Hz refresh rate. It scrolls up and down much better now. (seems faster too although i can't imagine how a refresh rate would increase scrolling speed lol... just my imagination I'm sure). It may just be that it's just not happening right now (it never was 100% of the time). But so far since changing the refresh rate I've seen no tears in the browser.

Not up to any more F4 at the moment but I'll get back into it before the day is over and see if that made any difference.

Alright - my thoughts were that it may be an Optimus problem, since I've had plenty of issues with it in the past as well.

Switching to 75Hz should alleviate the problem at least, as now your GPU has to render in excess of 75FPS in order for you to get any screen tearing.

Wish you well and hope you get to build your new rig soon ;).

Yeah, my last laptop had that optimus shit... and it DID give me problems with several games. I swore I would never buy another with it and won't. This laptop doesn't have it despite being much newer than that last one.

And thanks. I wish you well and yours well also. Stay safe.

I am playing around with NixOS.

It has atomic upgrades.

Yeah.

Ah oops, I think I used your post for the shortened OFG's quote XD
