Question Low GPU utilisation in DOTA 2 ?

[Archie_8]

I just change my GPU from GTX 1050ti to RX 6600, using Ryzen 5 1500X CPU.
My GPU usage is shown as below 30% (sometimes only around 10%), and CPU usage only 50%.
With 1050 Ti the FPS could reach 100++, but with new 6600 it can't even manage 100 in game, average is 40-60. Settings in game were the same and temp is below 70.

Please help.

did you use ddu to remove nvidia driver before install amd driver?

With a GTX1050ti, your gpu was loafing.
Now with a 6600, the new gpu is loafing even more.
Do not be seduced by 50% cpu utilization.
That is the average over 8 threads.
The critical single threaded master thread is likely closer to 100% and that is what limits you.
The processor is what generates the frames to be presented to the graphics card.

A more effective upgrade would have been to a stronger processor.

i think so, cause i ask the seller to install the rx

so the problem in processor bottlenecking my gpu rite? any suggest for minimum cpu i should get? i used asrock 320m-hdv now. im on tight budget rite now

geofelt's post doesn't explain why you went from "100+", to "cant even reach 100 in game, average 40-60".
That's not how single core limitation is supposed to occur; with the new gpu, performance either goes up, or it stays about the same. It's not supposed to go down like that.

That's not a solid confirmation that it was done at all. Run DDU too, please, to make sure the Nvidia driver is gone, and update the AMD driver after.
IF that doesn't bring you back to the previous card's performance or higher, THEN try updating bios.

Ok ill make sure nvidia driver is gone.
But for some games like ow2, black dessert, sons of the forest performance card was good. Only in dota2 this issue happen, and in battlefield V got 80 - 100 fps but game looks stuttery.

Graphics cards and drivers can differ on how they are implemented.
Particularly between radeon and nvidia.
Game coding may differ also.

Still, given equal processor capability, I would not expect to see a performance drop,
There may well be something else going on.
"Could reach 100+" and "can't manage 100" do not sound all that different to me.
How is the fps being measured?


As an experiment, go to windows power settings and reduce the max cpu% from 100% to 70%
If you see a big difference, then you are likely impacted by cpu processing power.

What are the rest of your parts?

Stuttering is a temporary lack of a critical resource.
Usually, this is cpu, but it could be ram or insufficient threads.

Sorry my english are not my mother language. Fps measured you mean what?

I planned to change the cpu to R5 3600.
Here is my spec now
Asrock 320m hdv r4
HyperX 2x8gb 2400
R5 1500x
Xfx Rx 6600
Enermax 500w

I've done DDU and detected my old gpu 1050. I clean nvidia also amd with ddu, then reinstall AMD driver. But same problem in dota 2 still occur.

I wanna try update bios, but I read in asrock website its kind a complicated to update. And also if I got 1 step wrong my system prob couldn't boot at all. Thats worried me

Does your performance satisfy you now?
If yes, game on.
If not, wait and see how much benefit you get from the planned 3600 change.
My guess is that you may do well enough.

On the bios updating thing, first, look to see if a bios update is necessary to support the 3600 or to fix some other issue that is impacting you.
Do not update the bios on speculation.
With newer motherboards there is no longer a real chance of bricking the motherboard from a failed flash.
Losing power while flashing would be one cause.
More commonly a user gets impatient and cancels the process prematurely.
A flash may take 15 minutes or more with nothing apparent going on.
If you have a shop available, pay them to install the 3600 and do the flash if needd.
But, the recovery process may be difficult.

For some games yes, some games were stuter but i know its because my cpu holding mu gpu. But for dota 2 really annoy me with that issue.

I do small research my mobo are p4.0 series driver. And 3600 are p2.0 series driver. Should be fine i guess.
