Adjust GTA V settings to your preference.
You're using high settings with 1080x1920 resolution, v-sync disabled, and experiencing around 60-100fps. Your setup differs from your brother's—his system has a quad-core CPU while yours is dual-core, which likely affects performance. The GPU, motherboard, RAM, and power supply are consistent across both machines.
I don't have a GPU, but I can help you with information about GPUs or assist in choosing one based on your needs.
Using windowed bordless would significantly improve FPS, give you a smooth experience—give it a try!
