Thanks for sharing these helpful steps on how to make GTA SA use an external graphics card. It can be frustrating when games don't automatically use the dedicated graphics card, so it's good to know how to fix it. I was considering buying one of the cards on https://finalratings.com/the-best-graphics-cards-for-vr-in-2023-performance-prices-and-recommendations/, but I'll also check out your advice as soon as I can. Thanks again for sharing!
