As you can see, temp wise i'm fine.
But here is the problem, you can clearly see that the GPU utilisation is nuts.
Micro stutters happened on Helliion as well at the time i had it.
It turn out that disabling freesync on my Iiyama GB2488HSU-B2 and in the Radeon software solved the problem on Hellion and Blackwake.
Now i was wondering, what the ... cause that ? because i have plenty of horse power to maintain 144FPS stable on Battleborn.
Is it caused by some games who don't support freesync ? i thought, correct me if i'm wrong, that Freesync technology was only concerning monitor and GPUs.. ?
Second question, on the graph you can see a max temp of 75°C. (because i played a good amount of Escape from Tarkov before.)
What is the max safe operating temperature for a XFX GTR 480 ? 80°C ? same as Nvidia cards ?
I am not an expert on freesync just made own yesterday and still learning but I did come across some posts on how certain setting combinations will have all kinds of adverse affects with freesync from a lead AMD tech person. Here is the link and will post what he stated.

Do not use any sort of frame capping with FreeSync. The frame time analysis algorithms that govern FreeSync, FRTC or other methods will conflict and break both solutions. It's unnecessary. Here's why:
The only time you'd want to turn off vsync with FreeSync is if the app's FPS can go way above your monitor's max refresh and you want the lowest possible input latency at the expense of a little tearing at high framerates. FRTC is the antithesis of this, so it doesn't make sense to use FRTC in this case.
If you're not trying to get the lowest possible input latency, or the app's FPS stays inside your monitor's DRR window on the regular, then leaving vsync enabled will cap your framerate anyways. FRTC is redundant.
FRTC is for people with regular ol' monitors who are playing low-demand games running in the hundreds of FPS, which just burns power and runs the fan faster than necessary."
and This are the big things:

FREESYNC WITH VSYNC
If vsync is enabled, it is only active when the FPS is above or below your monitor's refresh rate range.
If FPS is below, the monitor has no choice but to use vsync in the double or triple-buffer mode you've set. This will avoid tearing, but add input latency.
If the FPS is above, the GPU will reject frames ("FPS cap") to keep the application inside the FreeSync window. It will enforce smoothness. You won't get the lowest possible input latency due to rejected frames, but no extra latency is being added.
When your game is in the FreeSync window, this is the lowest possible input latency.
FREESYNC WITHOUT VSYNC
If you really care about input latency, then you can turn vsync off.
If the app is inside the FreeSync window, FreeSync is active. This is the lowest possible input latency.
If the app is below the FreeSync range, monitor will run at max refresh until the app's FPS gets back inside the DRR window. You will experience tearing, but no frames will be buffered or held as with vsync.
If the app is above the FreeSync range, monitor will run at max refresh and your FPS can go however high it will. This sustains the lowest possible input latency because no frames are being buffered, held or rejected as with vsync. You will experience some tearing until the FPS falls back inside the FreeSync window and FreeSync resumes.
IF YOUR MONITOR IS COMPATIBLE WITH FREESYNC LFC
If your monitor has a sufficiently wide range to support our Low Framerate Compensation feature, this supersedes your vsync setting. It has lower input latency, no tearing, and no vsync stutter. It's much better than vsync.
Most people want to leave FreeSync + Vsync enabled.
PROS: GPU won't waste power/heat/noise on unused frames, game forced inside the FreeSync range as often as possible, no stuttering, no tearing.
CONS: Lowest possible input latency will not be achieved if app goes outside of FreeSync range. Vsync stutter possible when app is below FreeSync window.
If you're a stickler for mouse latency, use FreeSync + vsync OFF.
PROS: No stuttering/tearing inside FreeSync window, lowest possible latency at all times.
CONS: Tearing possible when app leaves FreeSync window
IF app FPS < min_refresh THEN Low Framerate Compensation (LFC) supersedes vsync.
I am not sure if this will help you or not. I just did not realize that all these do not work well together.
