Variable input lag ?
Variable input lag ?
Recently I've been searching for the ideal configuration to achieve 30 fps. After weeks of browsing, I've reached a conclusion about what works best:
-driver-level 1/2 vsync (in NVPI)
-RTSS external lock at 30 fps
-set maximum pre-rendered frames to 1 to reduce input lag.
The issue here is clear. If I follow all the steps, I should get a steady frame rate with consistent timing. But if I switch between menus or inventory screens and then close them, the input lag will change—specifically increase. This frustrates me because I'm unsure which settings need to be adjusted or changed to eliminate the variable IL effect.
I discovered a post on Blur Busters discussing the same issue (that's where I learned about it), but no clear solution appeared. People just discussed their tests in different games.
Thanks in advance for any help.
Update your post with complete hardware details and operating system information.
What are the current stable framerates or frame times?
After making adjustments, are you confident that changes are being saved through a "SAVE", "OK", or "YES" option?
It's possible the settings are off-screen; you may need to scroll to locate the save option.
As requested, I made the necessary updates. The framerates remain consistent at 30 and 33.3 according to MSI afterburner. With NVPI set to half refresh rate, the maximum pre-rendered frames are at 1, and FPS is locked at 30 using RivaTuner. I'm currently testing in CP2077. Initially, everything works well after loading, with acceptable input lag and smooth performance. The noticeable changes only appear when I switch between menus or adjust graphics settings. I’m certain these fluctuations aren’t due to the gameplay itself but rather interactions with menu options. It’s enough just to open the Map and change layouts like Journal to trigger the lag.
Make and model of power supply unit?
Wattage, age, and condition (original, new, refurbished, used).
Disk drive(s): brand, model, capacity, current usage.

"(I'm certain that any other explanation for both the FPS drop and the frame time drop would lead to the same result, it's just that I haven't identified these causes yet)."
Attempt to uncover the cause of the dips using Task Manager, Resource Monitor, and Process Explorer (Microsoft, free).
Use all three tools one at a time.
Open each window and adjust settings or perform actions that trigger the dips while monitoring the changes.
Observe which resources are consuming more than usual (percentage) and identify what activity is involved.
Changes may appear just before or during the dips; it might take some experimentation to find a consistent pattern, but don’t rush.
If the dips happen when a specific resource reaches a higher usage level, investigate further.

Sure, I understand. Thank you for your response. The testing will require some time, possibly a few days or a week depending on the plan.
