I use Opera GX with hardware acceleration enabled
Intel core duo 2.22Ghz, 4GB ram and an awful onboard video with a measly 256MB of memory

I see. Probably the computer specs are a bit low for the game.
You should seriously consider getting a newer PC. That's a 15 year old processor you're using there. Pretty cool that it still works to this day, but it may be a bit slow for comfortable gaming. A dedicated GPU will help a lot too. If you don't plan to game often, just get the low spec ones and it should be fine.
