Hi Atlas!

For the record, all testing from here onwards (unless stated otherwise) will be on Second Life Release 7.1.11.11750364439 (64bit).

I can confirm this happens regardless of the location. Just as soon as things start to get taxing, it'll begin to flicker until the viewer is restarted.

I've attached two videos below, the first of the viewer on the low graphics preset (with advanced graphics settings visible) and the second on it's lowest again (along with anisotropic filtering disabled as this is still enabled in the low preset and I didn't notice first time) using the Test Male avatar from the develop menu. I've also attached the logs which should include those attempts as well.

The flickering is less intense on the lower settings but that's honestly consistent with my experience so far, the more graphically intense the scene, the worse the effect.

If you need any other information, just shout. :)

Thanks for checking, Tsunade!

Some other things to try:

So, after some testing I can confirm the following things.

Vsync has no discernible affect off or on regardless of the settings changed below in the next section.

I've never configured any nVidia adaptive frame rate settings that I'm aware of but I investigated regardless, first by checking the nvidia control panel. Inside I found that the settings for "Power Management Mode" had been set to "Prefer Maximum Performance" instead of the default "Use Global Setting (Normal) and the "Threaded optimization" setting had been set to On instead of the default "Use Global Setting (Auto)". Reverting these changes (still no clue how they were made, my last full re-install was only a few weeks ago) does seem to have raised the threshold for how far I need to tax the machine to trigger the flicker, but not eliminated it. I did try re-enabling each one on their own before re-enabling both in case one stood out as an indicator, but having just either enabled on their own yielded the same results as if they were both off. Re-enabling both of them made it easier to trigger the flickering again, for future testing I'll leave these settings set to "Use Global" unless advised otherwise. I was not able to locate any settings in either the control panel or new nvidia app relating to adaptive frame rate.

I left my viewer logged in for a while and found the temperature of the GPU rested just under 60C and when pushed, didn't seem to increase much beyond. Additionally, the usage seemed to hover at 50% (which seems a little low) unless alt+tabbed out at which point it dropped to 12-15% which is expected.

I have two monitors, both of which are Gigabyte G32QC running at 2560x1440 at 165Hz on a DisplayPort and both with GSYNC support which, according to the new nvidia app is enabled on both. (I also have a valve index connected to a HDMI port which sometimes registers as a monitor in bios or a webcam and a dummy HDMI connector for use with sunshine/moonlight game streaming since displayport monitors stop registering if they're off, for the sake of these tests, these were both disconnected in full) I tried unplugging and testing with each one individual but this doesn't seem to have had any affect.

I got the notice that a pair of Lindens and someone else came by my sim and my orb went a little nuts. I've just removed the land bans (though I doubt that affected lindens) and also added the three names to the orb if you need to make subsequent visits. I assume you found the location from the videos in the ticket. :)
