Hey, not a stupid question at all — we’ve all been there when starting out with DMA and Fuser setups.
To answer you: yes, the resolution needs to be the same on both PCs — the one running your game and the second one doing the ESP overlay. If they don’t match, your ESP will be misaligned, stretched, or just not show correctly.
So even if you prefer 4:3 stretched in-game, you’ll need to make sure that both your main PC (with the Fuser) and your radar/second PC are set to the same resolution and refresh rate. It’s the only way for Fuser to overlay the ESP properly on your screen.
I know it’s a bit annoying to adjust, but once both outputs match, everything should line up perfectly and you won’t have to mess with it again.
Everything sent to the Fuser must be identical—same resolution, refresh rate, scaling—so it can perfectly layer the ESP output onto your main monitor without distortion.
