Thanks for the reply shiburizu!
I do use a 144 Hz monitor, except the only problem is it doesn't have any VRR tech like GSync/FreeSync, so I guess that'll have to wait for a while 🙁
As for your other points:
Setting Low Latency Mode to "Ultra" in Nvidia Control Panel if possible.
What exactly is this option, and when should I enable it?
I thought this option was only available for GSync monitors, but now that I look at my NVCP, I see that I have it available as well.
Also, I see that it comes with two options: On, and Ultra
What is the difference between these two, and which of these would you recommend me to use and when?
Using Exclusive Fullscreen Mode wherever possible.
Just to confirm, Exclusive Fullscreen Mode is simply ALT+ENTER-ing a game from a windowed mode to fullscreen, right? It's not some option within the game that's different from the "regular" fullscreen mode.
Sorry for such a dumb question, I'm too sleepy right now 🙂
Got it! But does this work for arcade sticks as well, as that's what I play on?
Many tweaks exist on a per-game basis, check PCGamingWiki or reddit threads depending on what you're looking to play but the above is the most general I can get.
Already knew this, but thank you for mentioning it! Not many people remember (or even know) about PCGW, so it's good to see someone else recommend it 🙂
