RX 6600 low gpu usage. Help!!

[BBaron5jd]

Hey guys,

I got an RX 6600. upgraded from gtx 1660, hoping to get a bit more fps in my games.

But after installing the card, I immediately noticed stutters. When I checked the gpu usage, I saw it hovering around 70-80% and sometimes dropping below 50 (as low as 0%). I checked a lot of benchmark videos and PCs with slower CPUs have higher fps/scores. I am running an R5 3600 without overclock, but SAM enabled.

Some games are using a lot more CPU than they should (also seen from those videos). I used to get stable 60 fps on high settings in most games (rarely dropped to 50s) using the gtx 1660. but now I feel like I downgraded my gpu since I am getting lower fps in the same settings. However, I noticed that I do get normal gpu usage in rare cases and I get normal fps at that time. Often right after booting in to windows. But most of the time, it's bad. I'm going crazy here. I can't find a single solution. The only "fix" is to remove cpu bottleneck, but I don't see why my pc would be a special case specially considering I used to get better performance from a gpu that should be slower. 

 

My temps are fine; below 80C. Power usage fluctuates with gpu usage. 

 

I tried these:

1. DDU all gpu drivers

2. delete cache

3. Uninstalling afterburners

 

 

Specs:

R5 3600

Rx 6600

16gb 2666mhx DDR4 

Windows 11

What board do you have?  Could be running at 3.0 gen PCIe.  I think it was only the 5xx boards that had pcie 4.0

Yes. It's running at pcie 3 8x but I don't get why I would get lower fps than those youtube videos with the same specs.

Gen3 x8 would not limit an RX6600 in any way.
