I have R7 260x XFX 1gb edition. Not the best gpu, but uni fees and just surviving has its toll on my gaming.
My main game is Dota 2 and recently with this gpu i had some clock drops, but I just got used to it.
Until one day in dota my fps droped after some time playing .Other games work fine, dota dosent. I try reinstalling drivers, monitor my performance all kinds of stuff, and in the end I had to switch to my older (yea, i got one thats older) gpu.
Few days ago I tried R7 once again but this time I did not download drivers from web, but in win10 devmgmt I pressed auto update.
And my GPU works better than ever.
I only have one problem. Recently I got No Mans Sky, and I cannot play it because I get this error :
Vulkan Initalization Failure
Unable to initalize Vulkan (vkEnumerateInstanceExtensionPropertiesfailed.) You may not have a Vulkan driver installed, or an old driver on your machine may be corrupted.
I am not gonna install drivers from web again, as it causes problems.
