Drivers & Software

I have a RX 460 and Ryzen 3 1200 CPU. I am having issue playing specific games. The major issue is with Fallout 4. In this game my fps drops from to 20 in specific areas. I play this game at ultra at 1920x1080 resolution. In all the videos I have seen so far this game seems to run fine on my card.Here are the videos-

AMD Radeon RX 460 -- Intel Pentium G4560 -- Fallout 4 FPS Test - YouTube

I am not able to find the cause of this issue but one thing I have noticed is that my CPU usage never rise above 25% in areas where fps drops occur and remains constant.I have attached a image to clarify the issue.My specs are-

CPU-Ryzen 3 1200 3.4GHz

GPU-RX 460 4GB

RAM-8GB DDR4 SINGLE CHANNEL

MOTHERBOARD-AB350M GAMING 3

PSU-VS 450

WINDOWS-10 1809

I have tried clean installing windows, GPU and chipset drivers and I have updated BIOS to latest version. This issue is not present in older drivers as evident from videos. But I am not sure if this issue is only with my system.

EDIT:   I have noticed in my events manager that I get error starting one component while installing drivers. I have attached file.

Assuming Ryzen 3 supports a dual-channel ram configuration, I would suggest adding another 8GB stick of DDR4 into the appropriate slot on your motherboard.  You are doing yourself a disservice by sticking to single-channel DDR4 configuration.  Here's an example to ponder for reference:

No dual channel RAM does not affect performance of budget GPUs like RX 460. The video you have posted is for APU for which dual channel is necessary but for a discrete GPU it does not effect. Here is a video-
