Ryzen 5 1600 GTA V using two cores.

[deirojeremy]

I have just upgraded to a ryzen 5 1600 and when I play GTA V I noticed that it is only using two cores. This is causing the framerate to drop significantly and it only happens in GTA V. Is it an issue with the game or processor. Is there anything that I can do? I have tried updating the drivers they were up to date.

My specs are:

Ryzen 5 1600
Gtx 1060 3gb
8 gb ddr4 2666

Fresh Windows install or swapped drive from another machine?

 

[deirojeremy]

I installed the cpu in an existing pc.

Seen that you edited, it did say before you swapped the hdd in answering dudeman's reply if it was a reinstall or hdd swap.

Swapping Windows can cause these issues without reinstalling.

I suggest opening msconfig (type msconfig in task bar search), go to boot > advanced options > and checked the box number of cores and select how many then restart. If this box has already been checked, uncheck it and restart the pc.

All of the cores are there but for some reason GTA V will only use two cores. In other games every core gets used. I don’t know if it just what GTA does or if I can do something about it.

In task manager right click gta 5.exe and click affinity. What do you see there?

 

[deirojeremy]

All of the cores are checked.

 

[boju]

Where did you get the game from? Have you verified the game cache if on Steam?

How are you monitoring cores?

 

[deirojeremy]

I don’t have the game through steam I bought through the social club. I have been using afterburner.

Check task manager core graphs

 

[deirojeremy]

It shows 12 cores but during GTA two cores are at 100 the rest are almost at 0.

 

[boju]

What cpu did you have before? Would there be any reason why gta5 thinks you only have two cores?

If you did have a dual core system previously, a reinstall of the game might be worth trying.

Only explanation i have sorry

 

[deirojeremy]

I had a Ryzen 3 1200. I guess I will just try to download the game again though, thanks for your help.

 

[boju]

Let us know how reinstalling goes and feel free to unselect best answer if it doesn't work.

 

[deirojeremy]

I tried reinstalling the game that did not help. Thanks for the suggestion but I am not really sure what else I could do. Do you think reinstalling windows would work? I would rather not do that to play one game when everything else works.

I just realized that if I turn the graphics settings all the way down it will use all the cores. But turning them back up makes use two cores again. Could this be do to the boost of the cpu and if so how do I disable it?

That is very strange. I have the same system (except a GTX 970), and it loads up at least 8 of the threads in task manager.

 

[deirojeremy]

Yes, it is very strange and I am not sure what to do. The game used to run better on my Ryzen 3 at the same settings and I do not know why.

 

[boju]

No idea what gta5 does differently to other games. Lowering graphics doesn't make any sense.

Have you tried while playing the game set affinity to like 4 cores then go back to game, alt tab then select all cores again?

 

[deirojeremy]

I did try that when I set it to four cores it only used one. Then changing it back it used two again.
Lowering the graphics only worked at the absolute lowest settings with 800 x 600 display.

 

[deirojeremy]

I guess I will just hope that eventually something happens to make it work. Thanks for help.

 

[boju]

And you're monitoring cores while playing not in the menus yeah?

 

[deirojeremy]

Yes, it is while playing. The first and last cores are always at 100 and the rest never go above 10 and the framrate drops down in the 30s. Gpu usage is about 60-70.

 

[boju]

Did you ever reset cmos and then load bios defaults afterwards when you changed cpu?

 

[deirojeremy]

No, I did not. How would I do that?
