My spare pc has an i5 2500 and I experimented with several cards like the GTX 750, GTX 950, and RX 570 XT. If you are on Linux, you can disable your iGPU to only use your dGP with a modprobe. i915.modeprobe=0 goes into your boot config for however your distro handles it. The i5 2500 would crash if combined with a dGPU on KDE, cinnamon, or other desktops. I don’t think this is a Minecraft issue so much as an intel iGPU issue. Intel Arc are dGPU, not iGPU, so this isn’t a duplicate.
Please attach a performance report whilst running the vanilla game.
