First, I acknowledge my system is very old and the processor is weak. I bought the A770 LE some months ago just because I really wanted it (it was being discontinued) and because I already planned a system upgrade by the end of the year.
My gaming rig comprise of a Xeon E5 1620v2 (slightly overclocked at 4.4 GHz via base clock), 16 GB of DDR3 ram running in quad channel at 1866 MHz and, now, an ARC A770 LE.
Before the Arc I had an RX570 4GB.
What I noticed is that the performance of the ARC gpu is much worse than the one of the RX570, specifically in Overwatch: while with the old RX570 I was able to lock on 144 fps without issues, with the A770 I see fps as low as 80 in some scenarios (usually when there are multiple characters on screen).
Also the usage of the CPU stays at around 50-60%, while for the GPU is 40-50%.
I really cannot think of an explanation for it: why would a much more powerful GPU perform worse on the same exact system and settings? Could it be a DX11 driver optimization issue? (in Cyberpunk, that is DX12, the ARC is performing as expected).
I was expecting to have at least the same performance while waiting to build the new system…
PS: thanks to the ReBarUefi project, I have Resizable BAR active.
Borrow a PC from your friends for a weekend and try the GPU there.
If there’s a problem with the GPU (for example it’s overheating due to not sufficient die contact) then return it or RMA.
If it works then look at upgrading your PC.
Go for an X3D CPU from AMD, or wait for the new desktop CPU from Intel next year because they’re going to switch motherboard sockets again.
