I'm using dedicated AMD GPU (HD 8570M) and it's installed correctly in my system.
*-display description: Display controller product: Sun PRO [Radeon HD 8570A/8570M] vendor: Advanced Micro Devices, Inc. [AMD/ATI] physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list rom configuration: driver=amdgpu latency=0 resources: irq:26 memory:b0000000-b7ffffff memory:b8000000-b803ffff ioport:4000(size=256) memory:b8040000-b805ffff
But upon playing game in Wine— it is barely playable, in Windows they DO ran smoothly, and I can confirm Windows actually uses the GPU. I suspected Wine uses my integrated Intel graphics instead.
How would I check that in Wine ? Is there any easy way to figure it out?
