If you haven't already, try rolling back to an older driver and see if that resolves it.
If it does, then you may have found a bug and it would be worth gathering enough information to help identify and correct the bug.
(They do happen after all...)
Previously, I had rolled back to 15.6 and 15.5 without any sucess; however, I decided to go back to 15.4 and I can report that the issue is completely gone in that version. The only downside is that the game sometimes freezes when I'm trying to exit it, but otherwise it runs like it did before.
I still have the same problem even with the latest driver version 17.1.2
Fragments everywhere but no solution?! Also there are fragments on the loading-bar or life-bar of hostile NPC's.
Another thing is the fps drops in video sequences.
I know this is a very old thread... But the problem persists.
I am a proud (am I) owner of an ASUS DUAL RX480 4GB. Every game runs perfect, even in 1080p.
I usually use 900p (my screen is 900p but tried stuff on 1080p tv).
Since a year or two (can't really recall) I had many problems with the SW:TOR UI. No other games. Only SW:TOR.
Weird artifacts appear when I hover over the skills in quickbar, my exp/legacy exp bar are flashing
and usually I have a vertical and a horizontal line next to my minimap, which are supposedly parts of the minimap because I can see the map through it.
Now, I have figured out two solutions. For the artifacts and lines and flashing, setting everything to a 0,85 or alike size in Interface Editor is working 99% of the time. On the other hand, if I set Anti Aliasing to or below Medium, every issue are gone.
But that's plain stupid.
I have recently tried rolling back to pre-crimson drivers. Only made my PC not recignising them. Too old for my RX480, I guess.
But I can easily run Skyrim SE on MAX settings on 1080p around 60 fps. So SW:TOR having graphics problems because of AA over 2x samples is BS.
AMD, please fix this. Or do sth with EAware, and fix it together, idc. I have not paid for the RX480 to use 2x AA.
Sorry if I sound butthurt, but this is getting ridiculous.
