A lot of people are being seduced into installing Win10 on machines that are too old (a release date around May '05
for the Intel 82945G Express Chipset Family), because of MS's 'free' offer .
You did well to run Minecraft at all with an integrated graphics (GMA 950) of that vintage,
and I would have been somewhat surprised that driver support didn't stop with Vista.
- Unfortunately you cannot upgrade integrated graphics, and if you are using a laptop you cannot install
a dedicated graphics card.
If you are using a desktop PC you also need to verify the power supply has adequate watts/amps for whichever
graphics card you install.
You also need to verify the motherboard has PCIe rather than AGP graphics slots.
- Why only Minecraft ? Perhaps the other games you have installed have lower requirements.
eg- 'Point and click' style games with static, or mostly static, 2D screens may look nice, but don't require
much processing. Minecraft may look basic, but can be more system intensive than it looks.
