Will wait and see if a fix will be availible for older cards...
This is exactly where my mind went too. I have a feeling Nvidia and/or Microsoft is going to use this as an opportunity to force people to buy new cards and/or move onto newer Windows in order to receive the fix. I hope I'm just being pessimistic, but that is the vibe these corporations put off nowadays, so I don't think it's unreasonable to think this.
 
PS, i said "in News(News and CHAT)", not as news :rolleyes:
Please feel free to merge it over. I thought about posting it there first, but since this was such a hot topic I figured there would be a lot of responses. Also, I suspected we'd get a few people that wanted to rehash topics from the locked thread too, or some guys posting DPC issues and screenshots here, since we struggled so much with getting peeps to follow directions, so I didn't want them to muddy up that news and chat thread.
 
all this time, all these posts on the interwebs and nvidia didnt know about high dpc? BS!
pull the other one, its got bells on :mad:

The question is whether nvidia considers this a new bug introduced in the new drivers or if it is a bug that has existed for years as we know according to reports on the internet. If it's the first option then nvidia won't solve this old problem. So I wouldn't have high expectations.

I personally have no dpc latency issues even with the new drivers.

This is a difficult problem to deal with because not all hardware has it, it is difficult for nvidia to reproduce this. I think it's not just nvidia to blame. Probably Windows too. That's why it's important to keep Windows up to date if you have any recent versions because Microsoft changes these builds very frequently which causes problems with certain programs and drivers.

I'm having stuttering with Chrome and YouTube (and other sites that play videos too). In older drivers this does not happen. I suspect it was something new that nvidia implemented using some api from Microsoft. Probably related to Multiplane Overlay (MPO).

If I disable Multiplane Overlay (MPO) a Windows feature the problem is partially solved as I still see glitches on the page in a short time and randomly. Another solution is to change the "graphics backend for ANGLE" in Chrome from D3D11 (Default) to D3D9. So far this has worked best for me. In this case it seems to me much more a problem in Windows than in Chrome or nvidia. Even because this happens with AMD cards too.

What I mean is that maybe nvidia alone can't solve this and needs to work with Microsoft or even others like Intel and AMD.
