Additional Data Needed Regarding GPU Utilization Issues

Reporting the same issue, on an AMD RX580. More details below:

I stopped playing late Heavensward and only came back now, which I guess explains why I never had this issue before since it apparently started in 4.2 or 4.3.
I play at 1440p medium/high settings

- With framerate unlocked I play at 75-90 fps my card hits almost 77ºC and is permanently at 100% usage. This is beyond the 74ºC soft cap that I have experienced for months with literally any other game. Overwatch at 144fps? 74ºC cap. Witcher 3? Crysis 3? Forza Horizon 4? 74ºC cap. All at 1440p Medium/high settings, except overwatch which I play on low so I can maintain a 144fps lock.

- This intensifies on cutscenes. For some reason, during cutscenes, the framerate jumps to 100-120 and the card heats up even more, hitting 80ºC and unusually high power draw, along with louder and faster fans. In Addition to this, I've had a couple of crashes to desktop during cutscenes, with a DirectX error.

- If I use the game's settings to lock the framerate at 72 (1/2 refresh rate) the game locks to 13FPS for some reason. Changing to 1/4 refresh rate lock, further reduces that to an 11FPS lock.

- I thought it might have something to do with a v-sync conflict, so I turned Freesync off on my monitor. Try as I might, regardless of the combination of settings (driver vsync off, game vsync on, vice versa, both on, both off, with and without freesync, the issue always persisted, no changes.

- Capping the framerate using rivatuner/afterburner worked perfectly. Capping the FPS to a value even just slightly below what I actually get (locked to 72) resulted in slightly lower temps, lower power consumption and lower fan speeds. Cutscene issue persists. the GPU is still permanently at 100% usage, even though I get 72fps locked. which means the issue is still there, I just managed to slightly alleviate the symptoms.

- in order to get this over with I just ended up lowering the rivatuner fps cap to 60. The game runs at 60 locked, and as expected, this further lowered GPU temperature, system power usage dropped by ~35W when compared to unlocked framerate, lower fan speeds and noise.

HOWEVER, even with a humble 60 fps lock:
- GPU temp is still consistently higher than normal, still hitting 70-74ºC, which is insane.
- Cutscene issue still persists.
- And most astounding of all, GPU usage is STILL locked at 100% at max speed (1430Mhz core clock), for some reason.


Hoping to see this fixed, as this is a very serious issue and could cause unaware people with less than ideal cooling to overheat their PCs.
