FPS drop when focused on certain window

[BestestCohen]

Hi. Recently I've been facing an annoying little bug. When I use AutoDesk Fusion 360 or BlueJ, I notice that my mouse won't move as smooth as it moves on other windows, the windows are lightly flickers and once I refocus on Chrome, it turns back to normal (smooth mouse, 165hz, and no flickers).

 

• Windows 10 64bit
• I7 8700K (not overclocked), asus rog strix 1080ti (no overclock), Corsair CX650M PSU, 1 Samsung 970 250gb, 1 Samsung 970 500gb, 1 Samsung 860 1tb, Corsair Vengence 32gb RAM (4x8), Noctua D14, 3 monitors; 2 Dell S2417DG and 1 Samsung C24F390.
• BIOS version 2301
• Every time I use BlueJ or Fusion 360. Might be more applications but these two are my most used ones.
• When I focus the above's windows, my monitors start flickering slightly, the mouse feels alot slowly and not as smooth (I can see it's tracks when usually I don't) and once I refocus Chrome, it's all back to normal until I focus back the above's windows.

 

Appreciate the assistance!! <3

This smells like software but I’ve heard weird things about mouse drivers lately, so it might be worth looking at peripheral drivers as well.  Mouse and keyboard stuff.

It is normal for heavy applications to drop the fps.When they are not in focus they use less CPU resources, unless rendering. But that is more GPU heavy.

You might have better luck using some fps limiter, running those heavy programs at fixed 60 fps, should be smoother than jumping all over the place...

A point.  The only other app compared to is chrome which is much lighter weight than autodesk.  Could be big apps that stress your hardware do that.  I only recognize auto desk, but that is a heavyweight app.  Much heavier weight than chrome. If it’s your hardcore stuff doing that but things that aren’t hefty don’t have an issue it very well could just be that.

Thank you all for your time! I really appreciate it!

I forgot to mention, I reinstalled brand new Windows and checked with BlueJ(like Microsoft's Visual Studio Code for Java) and it stayed the same (before and after the reinstallation).

I have Logitech G502 Lightspeed. I see no update on their GHUB software for drivers. Is there anywhere else I should look for a driver update?

But shouldn't I7 8700k and 1080TI manage to keep it at 165hz? 

Maybe having 3 monitors connected to one GPU takes too much power off the GPU? (2 Dell S2417DG at 165hz and 1 Samsung C24F390 at 60hz)

Tried to run Fusion 360 as I opened the computer, without Chrome, Only Fusion 360, FPS drop still happens.

Having monitors that run at different refresh rates could be part of the problem.

Have you tried with just the 2 that support 165?

I just downloaded RTSS Rivatuner Statistics Server and it seems to resolve the problem!

Thank you so much everyone for your time and input!

[BestestCohen]

Trying my luck again.

The problem does not seem to be fixed. It returned a week after I thought it's over.

 

 

I thought maybe if I upgrade my 1080ti to 3080, will that solve the problem?

[BestestCohen]

Anyone?

People may have stopped watching after you listed the problem as fixed.  Might have to quote or link previous posters. With a gpu change you will change the driver and the hardware.  If the driver is the issue somehow or if it’s actually the hardware itself, it may change.  3080 is a bunch hotter though so a heat problem might arise or other new problems could be introduced.  1080ti is more tested than the 3080. Would be effectively a whole new set of things and one would have to start at the beginning.  The generic thing for most issues such as this is to do a clean reinstall with new, most recent drivers.  Just as easy with the 1080ti as with a 3080.  This may have already been done though.  I don’t know what going away but then coming back means.  Perhaps by changing software you emptied a cache or buffer that had to fill up again.   There were a whole bunch of suggestions earlier in the thread that got more or less short-circuited by the “never mind, I got it to work” thing. The whole thread would need to be gone over and the various things tried likely before anyone could even have much to say.

Make sure all monitors have the same refresh rate, Nvidia has known issues with monitors that run on different refresh rates (not unsurprisingly so if you think about it)

 

A 3080 will not change that.

I've tried to install a clean Windows and the first thing I installed was BlueJ (Java code environment) and the problem was still presenting.

I stated above that I have 3 monitors, 2 2k with 165hz and one 1080p with 60hz. 

I've tried unplugging the 1080p one and I saw no changes.

Do you think that this might cause the problem?
