I'm trying to wrap my head around how my boyfriend can still play games smoothly when his monitor is connected to the motherboard instead of the GPU. He built his PC about two years ago with a decent setup, using a GeForce 3060 graphics card if I remember correctly. Even though he's not running games on ultra settings, he still gets a pretty good frame rate, ranging from 50 to 120 depending on the game. He enjoys titles like Warframe, League of Legends, Monster Hunter: World, and Baldur's Gate 3. I'm curious if he's actually leveraging some integrated graphics capability or if there's something else going on that allows this performance. Can someone explain how this might be possible?

His performance sounds decent, but there’s definitely a loss compared to connecting directly to the GPU. Playing games without the monitor directly linked to the graphics card can lead to subpar performance, especially with demanding games.
It's pretty wild, but some motherboards can allow this kind of setup. I have a Ryzen board from a few years back that works similarly. It’s not the typical operation, though, so he might be getting a mix of power from both the integrated GPU and the 3060.
It sounds like his motherboard might have HDMI pass-through capabilities, which can let the GPU do some heavy lifting even if the monitor is plugged into the mobo.
Exactly! I've had a similar experience where my GPU was still helping out even with a monitor on the onboard graphics.
Did you guys consider just plugging the monitor directly into the GPU? It’s better to ensure he’s getting the most performance out of that 3060!
This, for real! It’s way underutilizing that GPU.
This might be a bit suboptimal, but Windows can allow the frame buffer from one GPU to be used for output on another. That said, it usually means you’re running into a bit of lag and losing some performance, too.

That makes sense! I know some motherboards support that kind of setup.
