I'm using a wide-screen monitor capable of 165Hz, but when I connect via HDMI, it's capped at 100Hz. In Overwatch, I get around 220-225 FPS with HDMI, which is great, but when I switch to DisplayPort trying to take advantage of the full 165Hz, my FPS drops to 115-125 with lower 1% lows of 75 FPS. This makes gameplay smoother over HDMI, which is really confusing. Can anyone explain why this is happening?

I checked your post history, and it seems like you're using a laptop that supports USB-C instead of native DisplayPort. That's likely the root of your problem.
It sounds like your monitor might have an older version of DisplayPort while HDMI is more updated. Check your monitor's specs for the supported versions. That could explain the FPS differences.
It has 2 HDMI 2.0 ports and DP 1.4. Is what you said about versions true?
If you still can't find a solution, it might be worth contacting the monitor manufacturer directly. They could offer more insight into what's going wrong.
I'm looking for possible solutions or what might be causing this. Like a faulty cable or any other reason that DisplayPort could use more processing power, I have no idea!
You might want to try a different DisplayPort cable. Sometimes the cable can be the culprit, even if it seems fine.
I unfortunately don't have another one. I bought this one off Amazon when I found out I needed a DisplayPort cable.
What kind of CPU and GPU are you working with? If you have an Nvidia GPU that's not a 50 series card, rolling back your drivers to December might help because the current drivers have been causing issues for a lot of users.
I will try this, thank you!
Yes, but when I plug in the USB-C cable, the monitor reaches 165Hz instead of just 100Hz with HDMI. Doesn't that mean it supports DisplayPort?
