High worst-case frame times in OW2?

[driedurchin]

I built a PC a bit ago, and have intermittently been debugging some high frame times. Let me know if this is the wrong forum/board to seek advice for this kind of problem, but here's my specs and what I've tried.

HWiNFO Report:

Here's a CapFrameX report that is the most representative of the type of issues I'm seeing:

If this isn't the kind of input lag this forum is for, suggestions for other forums would be appreciated, thanks!

This can be perfectly normal with some games (mostly Unreal Engine.) In fact, this is pretty good for something like Oblivion Remastered. I expected way worse than that

I forgot to mention my issues are in Overwatch 2, which for an esports title on this PC I expected to be perfectly smooth.

Check dpc and isr interrupts (by service and drivers) thru latencymon, check also that c-states are disabled in bios. Make sure your msi are setted up properly (I had issues with 5090fe that was running on single msi line and should be 8 in my case)

DPC and ISR through latencymon comes back green, I can post a screenshot if you'd like. MSI is enabled, but I haven't checked the line count. I'll try C-states but have heard conflicting advice on if that helps.

I lied, DPC latency is 1.2ms from nvlddmkm.sys. That was with C-state control disabled.

MSI Utility reports a limit of 1, and max of 1 for my 4070ti. The MSI box is checked.

This is right, about latencymon post a txt with the main result after 10 minutes playing, and post screenshot of driver tab sorted by highest execution.
