My card is a XFX RX480 8gb, using Displayport (AMD Radeon™ RX 480 Tuned by XFX - Custom Backplate XXX OC 1288 mhz 8GB GDDR5 HDMI 3xDP - RX-480M8BFA6 ) - Update driver yesterday 17.4.4 (no change from olders)
MB Gbyte z170m-d3h ddr3
Corsair Vengeance 16gb ddr 1600mhz
PSU Corsair 850W tx2
Monitor Benq 2720z 144hz (DP1.2)
Win 10, Win game mode updated.
I play all games on 1080p, set HARD.
After 10, 15 min or when there's a lot of action and effects on screen (like a full pvp on Paragon) my fps drops. Normally is 90 - 120, but drops to 15 for and stay that way for sometimes 30s.. always in critical moments.
On BF1 drops to 30 from 100 after playing a while. CSGO as well.
I set +50 power limit on Wattman. No change.
I don't know what to do anymore. Maybe change to Nvidia =/
