Relevant info

Win 10 22H2
PresentMon 2.0.1 64 bit CLI standalone
V-Sync globally disabled in Nvidia control panel
Game: Death Must Die
V-Sync enabled ingame (disabled caps the FPS to 120, enabled uncaps it (presumably due to NVCP V-Sync off))
Borderless Fullscreen (native HW: iFlip)
does not happen with V-Sync disabled ingame

The analysis can get confused while first starting up, because different events can be missing while the collection system starts up. There are some features that try to correct that, but I suspect that's what's going on here.

Did this just happen once, or is this something that happens consistently that we could try to reproduce?

Happened 3 out of 3 times so far

JeffersonMontgomery-Intel commented 3 months ago

Well, that's "good" for trying to figure out what's going wrong at least :)

We will try to reproduce this for debug, but if you're able to provide an ETL that captures this issue on your system that could help accelerate debug/fix. See instructions here: https://github.com/GameTechDev/PresentMon/blob/main/CONTRIBUTING.md#if-there-is-something-wrong-with-the-data-presentmon-is-reporting

Thanks!

Hello, we would like to verify whether you are still interested in resolving this issue. If so please provide an ETL file as per above instruction and we will diagnose your issue. Otherwise we will close this as abandoned.

BoringBoredom commented 1 month ago

It still happens in v2.1.0. However, I'm unwilling to upload an ETL file as it may contain personal data, according to the WPR warning:

Understood, thank you for your reply. We will make another attempt at reproduction on our side. May we ask what graphics adapter you are using?

RTX 3090
