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

With the pc off and unplugged, remove the watch sized battery on the motherboard. A round silver looking coin.

Leave it out for a minute or so. This will clear cmos. Put battery back, connect power then boot to bios. Click load bios defaults.

After doing so restart then go into bios again and redo any changes you might've done previously. If didn't change any settings previously just boot straight to windows.

Ok, I will give that a try when I get a chance.

What where you running before upgrading to the ryzen 1600?

 

[boju]

Was running ryzen 3 1200. Windows isn't a reinstall afaik. Reckons gta5 is the only game not utilising all cores. All cores are accounted for in Windows though.

 

[deirojeremy]

I haven’t reset the cmos yet because I don’t have acces to the pc at the moment. But I can confirm that it was an r3 1200 and I have tried about 10-15 other games and they all run as expected. GTA seems to be the outlier for some reason.

Did some investigating in GTA 5 of my own, did find some interesting things.

Task manager reflected the same as msi afterburner. Had msi afterburner show all 8 threads in osd for my 2600k.

During the menu the main 4 cores were being used, the other 4 threads (hyperthreading) were mainly sitting on 0% with slight fluctuations around 5% or so.

With Vsync set to half in game, if i stood still the hyperthreads would be at 0% with slight fluctuations if a car or person came by. If i moved though all threads would jump dramatically. What i found interesting is if i had Vsync in game set to on or off instead of half, standing still didn't have the same effect, most threads were at reasonable usages except for the last two which were still at 0% or bit over. Moving however, again, changed and usages across the board shot up.

In Nvidia control panel i have Vsync set to application control

Since your Ryzen has more cores / threads than mine usages will be different, probably less when work load is spread out more.

It is possible Gta5 just doesnt like so many threads going so possibly might help to disable Simultaneous Multi-Threading in your bios and just run 6 cores. Or maybe not, Dudeman reckons his cpu is fine but not sure what Vsync settings are being used. He'd have to investigate himself also if he was willing.

Thanks for the information I will try that too. I had read other places that GTA V should use more cores. I am not sure what each of the cpus in afterburner represent but it always uses the cpu1 and cpu12.

 

[boju]

Simultaneous Multi-Threading like Hyperthreading but AMD's version just adds another thread to the same core, so one core essentially becomes two threads.

So in afterburner your cpu would real like

cpu 1 - real core
cpu 2 - Simultaneous Multi-Threading

cpu 3 - real core
cpu 4 - Simultaneous Multi-Threading

cpu5 - real core
cpu6 - Simultaneous Multi-Threading

cpu 7 - real core
cpu 8 - Simultaneous Multi-Threading

cpu 9 - real core
cpu 10 - Simultaneous Multi-Threading

cpu 11 - real core
cpu 12 - Simultaneous Multi-Threading

The real core cpu numbers should have the more dominate usage.
-----

With Simultaneous Multi-Threading off, afterburner will read

cpu 1
cpu 2
cpu 3
cpu 4
cpu 5
cpu 6

---

2600k's hyperthreading reads the same but upto cpu 8.

You do have all cpus selected to be displayed in afterburner don't you?

 

[deirojeremy]

Yes, I have all the cpus selected. If what you are showing is correct than GTA V is using the first core which is real and the multi thread core 12.
I also have tried to reset the cmos but it did not bring me back to the bios when I booted my pc, I have tried it a few times and nothing changed. I have also noticed that I can only access the bios on my pc if it has been off for a while. If I try to restart my computer pressing the delete key to access bios just freezes it at the beginning and I need to shut it off and turn it on again. I have a gigabyte a320m hd2 motherboard.

 

[boju]

clearing cmos wont bring you back to bios automatically, still need to hit delete or whatever key you're meant to press to get there after restart. If that's not happening then you have fast boot on and bios is only accessible after a hard shutdown and not after a restart which'll bypass initial post screen.

Not sure whats going on there with the freezing. Not sure whats going on with cpu 1 and 12 either, whats happening with the rest?

If you have a spare hdd, disconnect your current drive and reinstall windows 10 and see if anything changes. If not well you haven't lost anything. If you install Win10 on another drive, disconnect all other drivers as Win10 will alter those, so just have the one drive connected when installing.

 

[deirojeremy]

Problem is when I reset the cmos the screen is just black until the windows login screen. I only have the ability to press delete to access bios when the gigabyte logo is visible otherwise it just freezes.
In the screenshot included in the first post it shows that the rest of the cpus are below 10%. When I play the game and drive around or do anything most them stay below 10% but cpu 3 will occasionally jump to 20% but thats it.
I do have another hardrive that I will see if i can get better performance on. So I will try that.

 

[boju]

Sorry didn't actually see the screenshot of yours. This discussion would've gone a different way, perhaps quicker but still very odd behaviour in gta5. Maybe dudeman can share a screenshot?

Not sure what's going on there with post freezing, might be collateral clearing cmos but doesn't sound right. If you can get into bios from cold boot, thats fine.

Clearing cmos was just something to try, should have been easier than this. Anyhow, doubt its bios related.

 

[deirojeremy]

I have yet to install windows on another drive but I just wanted to try something else. I reinstalled the ryzen 3 1200 as a test and it does the same thing. It uses cpu 1 and cpu 4 at 100% with cpu 2 and cpu 3 using about 20%

 

[boju]

Well id assume thats normal, and probably is normal too with 1600. Do you suffer any performance loss? While you have 1200 in jot down some numbers and compare.

Had another look at your pic, how long were you standing still there? Take a snap shot while you're driving.

 

[deirojeremy]

It does thing the same thing while I am moving. The 1200 is not really any worse the 1600 they both run at about 35 fps in the city in GTA. Both cpus run the game fine if I set the refresh rate to 30 in game or the vsynce to half. But shouldn’t I be able to run at 60 fps? The thing is I know that when I first built the pc at the same settings the game used to run at 60 all the time with an occasional dip down to 55. I know the 1060 3gb isn’t the best card but it only runs at about 70-80% at the most and the frames only drop when the two cpu cores hit 100. That leads me to believe that the cpu is holding me back.

 

[boju]

What resolution is your monitor?

Your right, both cpus should have no dramas running a 1060, probably more than 60 fps really depending on settings and antialiasing type like smaa of course.

With the trouble you're having its best consider a fresh reinstall of windows, clean slate, then we'll know where we stand.

 

[deirojeremy]

It is 1080p. The thing is that turning down the settings of the game doesn’t get more than 60 fps or even a steady 60 fps. I still get terrible frames in the city and I know when I first got the ryzen 3 1200 it used all four cores more equally than it does now. I guess I will install windows on that other drive and see what happens.

 

[boju]

Remember to disconnect all other drives before installing windows.

Lower res/details you go does put more load on cpu as gpu isn't used as much. That's not what you want. Want good 70ish combined cpu usage and 70~90 gpu usage. More work toward gpu the better. Resolution, details, antialiasing and view distance. Except ultra grass, that kills performance.

 

[deirojeremy]

Reinstalling windows did it. So now I just have to download everythin again. Thanks for the help everyone.
