I’ve created threads regarding multiple problems before, but have narrowed it down to just this now, so I thought I would create another. I can share the others and they can be deleted if needed.
I’m still getting nowhere regarding the main issue which are these spikes of low frame rates. Been through every driver version from 450 to 470 and none have made any difference to this problem. I’ve also got a new clean version of Ubuntu 20.04 and tested that and it has exactly the same problem.
At this point, some may suggest it is a hardware issue, but how can that be so intermittent? These periods of what feels like low frame rates occur so randomly, so is surely has to be driver related. Saying that, when I switch to the Nouveau drivers seems to not have the issue. While I can’t play games due to it not using the motherboard graphics as well as it could (still passing through the card), it no longer seems to have the random low FPS issue which can be noticeable when doing things as basic as dragging windows around the screen as they are choppy.
Just to be sure, I used Nouveau for over a week, and other than poor performing games, I never experienced the intermittent issue with any other program. I at one point wondered if it was related to lag from my input devices, as watching videos is perfectly smooth no matter what drivers I use, but watching others play 3D games while I stand still for example, the choppiness is still noticeable. It is just totally random. Sometimes totally smooth, sometimes a few frames per second. And it is exactly the same experience on my desktop with virtually no applications running.
If not using Nvidia drivers can help, surely there is a compatibility problem with my card, Ubuntu and the drivers all the way from 450 to 470. Before I had this issue, I never thought about graphics drivers as everything just worked, including the first month I had my new PC (all the way back in march). I believe it must have had 445 or below back then and it worked fine.
The other bizarre thing that is still the case is plugging another monitor into my graphics card seems to pretty much prevent these odd frame rate drops, but introduces other issues such as tearing. I’ve done a lot of research on this and I just can’t understand why I’m having such issues after having so many driver updates not fixing the problem. Also strange to not read up on anyone having the same experience. The only other possibility (that doesn’t seem realistic) is that this problem started to occur sometime after the first time I had used and them removed a 2nd monitor. I’m not sure if this or the driver update caused it. Surely the latter seems unrealistic though.
I am totally stuck with what to do as unless I find out it is a hardware fault, I can’t just send it back to the retailer that custom built it for me as there may not be any issues. I just don’t know how to find out exactly what they are. I still want to try the 445 drivers or earlier. I’ve tried “sudo apt-get install nvida-driver-445” but don’t seem to be able to fetch them.
If I can confirm that it is the card and software, then I think I will have to accept it and go for AMD instead. But I first need conformation of what the issue is, which I’ve been trying to work out for 5 months.
