This is a discussion on High FPS, but feels slow within the Video Card Support forums, part of the Tech Support Forum category. Here are my PC specs.
Ryzen 7 Eight Core 2700X 4.35GHz (Socket AM4) Processor
Gigabyte Aorus GA-AX370-Gaming K7 AMD X370
Do you have the latest driver installed? Do you have the Adrenaline software installed? If so, are you using it to OC? Is your RAM set to 3200mhz in the BIOS?
I'm not sure of that PSU brand.....That could be an issue relating to clean power not passing to the GPU.
On a personal note: I found over the years that while AMD GPU are good they're just not as good as their Nvidia counter part. When I made the switch from AMD to Nvidia, I never looked back. The down side is the price of Nvidia......but the bottom line is, you pay for what you get.
So bang for buck vs top dollar for better performance.....I'll take performance over price point anyday.
I've got a bud who has an AMD setup similar to yours. He has a Asus X470 mobo, Ryzen 7 3800X CPU, Gskill 3200mhz RAM and a Nvidia RTX 2080 Ti.....top that off with a 27" 2K monitor. He says that thing kicks some serious benchmark butt.
I've got the RAM back at 2400, at 3200 I was getting random black screen.
I'm planning on doing a new PC when the next line of AMD CPU's come out, also think I'm going to switch back to Nvidia. Or at least get rid of this Gigabyte card, it has so many bad reviews and I've already had to get 1 replaced under warrenty.
