I have an AMD Radeon (TM) R9 380 which, as far as I know, has 4GB of video RAM but now only shows 2GB on the system and it runs very poorly.
Playing the insanely buggy RDR2 I stupidly followed the instructions on the developer's page and DL'd 'amdcleanuputility' which promptly wiped all my drivers. The system couldn't recognise my card so I had to DL 'radeon-software-adrenalin-2020-20.1.3-minimalsetup-200120_web' to autodetect my drivers which it did. However when I check the system I get the following summary:
AMD Radeon (TM) R9 380 Series
Driver version: 26.20.15002.61
Driver date: 4/12/2019
DirectX version: 12 (FL 12.0)
Physical location: PCI bus 1, device 0, function 0
Dedicated GPU memory 0.4/2.0 GB
Shared GPU memory 0.0/8.0 GB
GPU Memory 0.4/10.0 GB
Frankly, I'm confused. Everything now states I don't have enough VRAM where before I DL'd that rotten program I did. Could anyone please give me some advice?
