Graphics

Hi - just entered the world of AMD GPU's - switching from Nvidia to AMD. Bought a new MSI 6900 xt gaming z trio - the one with the XTXH GPU. Tried the best I could to wipe out all Nvidia drivers etc. Now - when I run Timespy and port royale - I have 99 % GPU usage and it flies, but when entering games like Battlefield 5 or the new one Battlefield 2042 - I have GPU usage of around 75-85 % ?? v-sync off, all ultra.

Why not 99-100 % GPU usage ? Does the game still think I have Nvidia card installed ?

Next one - junction temperature. When running Time spy or port royale and 99% GPU usage I have around 67 degrees on GPU but around 105 degrees on the junction - and often hit 110 - that sounds very high. I know that I come from a Nvidia card - and here I could only get the card temp and not junction temps - but should I worry here ?

As a note - junction temp is very fast down to 80 degrees - and it goes up and down very easy. 

I've read that MSI did a bad design choice here. MSI say - if card does not crash - no problem !

Hope some here can tell me what I'm doing wrong.

What CPU are you using?

Was the GPU you had previously weaker than the 6900 XT? If so, that would explain the lower GPU utilisation.

Those games are very heavy on the CPU side and even users with the fastest CPUs see lower GPU utilisation in those titles when paired with a powerful GPU such as the 6900 XT.

Hi

cpu: AMD 3800 x

prev. gpu: asus rog strix gtx 1080 oc

but think I found some of the solution. I have a g-sync monitor and in Radeon driver it also says that my monitor is not compatible with Freesync and is disabled in the global monitor settings. But when I go to game tab and click on my game in the list to tweak things - (left is game tweak / gpu tweaks and right is monitor) I have at the top AMD Freesync setting - set as AMD optimized ! When I changed this to off my BF 5 then went from 75 ish fps to 160-170 ish fps - all ultra and 1440p !

Haven't tested on BF 2042 but guess that this is the same. Thought that g-sync and Free-sync did not matter that you could use both on whatever monitor but that is not the case.

So I think that first part is solved. The junction temp - I do not know what is normal - just think that diff. from gpu temp of 67-70 degrees to 100-105 degrees is quite a difference !

That's a normal and safe temperature.
You however can try to increase fan speed or decrease the power limit in Radeon Software > GPU Tuning menu and this will reduce the junction temperature.
