Question help me! my rx460 have a bad performance!

[goldmunds]

So i changed my gpu tu rx460 2gb. When i try to run bf 1942(it's first game in the series) i try it on maximum settings and it runs on 20-30 fps. My previous gpu was integrated intel hd graphics 124mb. So maybe i need to somehow disable the old integrated gpu?(with bf 1942 i mean battlefield 1942)

Welcome to the forums, newcomer!

What was your previous GPU's make and model? Did you use DDU to uninstall your prior GPU's drivers before removing the older GPU? After dropping in the new GPU, did you reinstall your drivers with the latest from AMD's support site?

You will also need to include your specs for added measure. List them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
