Unable to reach/maintain 60FPS (with extensive sidequest manipulation)

bamjus

I have a question. I am familiar with the performance/graphics tradeoff given the tools in sidequest, and have played around quite extensively with a bunch of different settings, even tanking the graphics to bring the FPS up to a consistent 60FPS (with seems to be the defaulted captured video FPS rate). Even in doing so, severely lowering the resolution rate, keeping 120hz refresh rate, increased CPU4, and playing with the FFR, whenever I check the FPS reader on the video playback UI IMMEDIATELY as i bring up the UI, it shows 30-45 FPS range. the FPS quickly jumps up to a maintained near 120 when the UI is displayed, as im sure the playback is less intensive that way. So my only measure of seeing the FPS display for the video playback itself is when I immediately open the UI and see the FPS it had been running at. Again, it somehow stays in the 30-45 FPS range. Im confused as to why I am not able to achieve a consistent 60FPS playback even when I load the quest2 settings for performance.

If anyone is able to shed light on this, how to optimize FPS to ensure 60FPS and therefore no frame loss on the majority of videos (and hopefully not have absolute awful graphics), please let me know what is the appropriate sidequest settings.

Thank you so much!!!

bamjus fiddling with those settings is probably what gave you the low fps... restart the headset so the settings reset to defaults and see if it fixes it. the app doesnt have the smoothest playback but it can easily do a reasonably steady 90+ fps on quest 2. getting 30-45 fps means you stuffed something up.

if you want a better way to monitor the fps then sideload the ovr metrics tool

spacepirate Thank you so so much for the help and for the info about the metrics tool. I restarted the headset and loaded the metrics tool which did show a consistent near 120fps without dropping below 90fps. Out of curiousity, I re-readjusted my sidequest settings to my 'ideal' settings which are a little more graphically intensive and the metrics tool still didnt show any drops below 90fps, which is great!! it seems as though the in-UI fps tool on DEOvr is significantly showing a lower fps (drops to 30-45s) reading than the metrics tool, not sure why. And i guess i may have been more focused on that display of 30-45fps than if I was able to visibly notice any frame drops lol, which is a good sign for the actual viewing experience. Thank you so much! this really helped!!

bamjus Playing back video and rendering 3D graphics (the UI) are two different things handled by different parts of your graphics card, or even different hardware depending on the system setup.

Decoding video with P and B frames + everlaying 3D rendered graphics is pretty workload intensive as the video is not decoded in a sequential manner.

An example, this is a common sequence, but it really can be different for every file.

Rakly3 Understood, that makes a lotta sense. Thank you for the explanation and visual!!
