Question Something Limiting FPS in-game.

[Hazard93]

Hello.

Recently purchased a new 1440p 144hz monitor, and a new RTX 2060 Super. For some reason though in games like rocket league, call of duty etc, the GPU is not hitting 100% utilisation. I've ran MSI overlay to check what's happening, and I don't seem to be getting an answer from that. All CPU cores are only hitting around 60% peak, so it's not the CPU, ram is hitting around 70%. G-Sync is enabled, along with frame limit being set to max on games, and v-sync disabled.

I'm also getting some weird micro stutter most noticeably in Rocket League.

Anyone who could help me out, it would be greatly appreciated.

System Specs:

CPU: Ryzen 5 1600
Motherboard: AsRock AB350 Mini iTX
Storage: 1TB Samsung 850 Evo SSD / Kingston 250GB SSD
PSU: Corsair RMx 650w
RAM: 2 x 8GB Corsair Vengeance DDR4 2400

MSI (as well as task manager) is giving you an average between all cores, it does not show you usage per core.
60% could mean all cores at 60% it could also mean that 60% of your cores run at 100% usage or anything in between.


As here, you can see that task manager is showing both cores at about 50% but process explorer shows us that it's one thread using ~50% of a dual core system so 100% of one core.

I suspect the slow RAM is a limiting factor.

Thanks for the reply Terry.

I have afterburner showing all 12 cores, so I can see each individual core. Is that not what I need to see?

Is there a way I can test that at all? I would've thought 2400 would be more than enough for 1400p 144hz gaming.

No, run process explorer double click on the game exe and look at the threads if you have one thread using up ~8% (100% CPU divided by 12 threads) then you have one core maxing out.

Issue resolved. Thanks for your advice though. I ended up just reinstalling Windows again, and it worked. Guess the system hardware was fine afterall. No CPU or RAM speed issues.

I think the issue lies with drivers. I was previously gaming on a GTX 980 before buying the 1440p 144hz monitor, everything ran fine, then I received my RX 5700 XT, used DDU to uninstall Nvidia drivers, then the problem started. I assumed it was the AMD drivers so I returned the card, purchased the RTX 2060 Super, and once that turned up used DDU again to remove AMD drivers and clean install Nividia.. Still had the issue.

I think maybe something within the AMD drivers effected the system, and obviously DDU couldn't change that.

Anyway, happy days. I now have a GPU that's performing.

Now I need to find out why G-Sync seems to be limiting frames. No FPS lock and V-Sync disabled. Not that I really care as I'd cap the FPS anyway. but seems strange. As far as I'm aware G-Sync should lock FPS to 144.
