Suddenly very low framerate, low CPU utilization?

[LiberiusX]

I rolled back to V 1.7.7 so I could give you some apples:apples comparison on the same machine, expecting to see a different experience.

Same issue. The game starts fine, averaging 50-70 FPS, but then starts to slow down. I suspect there is some hardware throttling going on. weird thing is my machine will stay noticeably slow even after I close Vicky 3, only a reboot gets the machine running smooth again.

Thankfully I have some tools to play with. will report back with any helpful data.

Edit: I moved some things around to maximize airflow for the fans. This has reduced temps by about 3-4c. I’m now maintaining close to 50-60 fps. So it looks like my issue was a heat problem.

Thanks for the attention.

Not at the moment...

But since 1.7.7 works fine, and since every other game, including CPU-intensive and GPU-intensive ones work just as they did before, I'm not convinced that there is an overall issue with my hardware other than perhaps compatibility. If someone else has a GTX 900 series card to test the new update out that would help a lot. Other than that, from my perspective, there was a shader update that broke the game for me.

While I don't know if there have been upgrades to the graphics in the game, it's not beyond the realm of possibilities.

Case in point. Way back (We're talking about at least 4 years ago here), I had an NVidia 750 ti in my then current system. It had performed perfectly for years, until I ran into a specific scenario in World of Warcraft where the performance dropped like a brick out of a plane. Instead of the usual 40+ FPS in that game, in this specific scenario it had dropped to something like 0.5 FPS (yes, a single frame took in excess of 1 second). Needless to say, that specific scenario was utterly unplayable. That scenario was also one of the then most recent additions to that game.

Long story short. I went out, bought an NVidia 1660 Super and dropped that in as a replacement for the 750. And, lo and behold, the stressed out frame rate in that scenario was completely gone. Apparently, that scenario used some kind of graphics that were different from the rest of the game world, and the hardware of the 750 was simply not capable of dealing with that in an efficient manner. The 1660 super, which was a couple of GPU generations more recent, was coping just fine with these graphics.

And since your GTX 900 series is based on the same Maxwell chip my 750 was using (although it's one refinement iteration more recent), the above situation may very well be applicable to your case.
