Crysis 3 random fps drop

[Rackooo]

Hello everyone.

 

I am having problems with runing crysis 3 on my main rig. I am runing on highest settings without aa on 1080p, (actualy the settings dont matter it happens at any settings). The problem is i mostly get 60-70 fps ocassionaly the high 50, but at random moments the game drops to exactly 32 fps and rises up again to 70. That happens by looking at the same spot mostly in a wall or something. I have tried many different drivers, disabling vsync (even tried force disable in nvidia cp). Did anyone else have such problems.

 

Specs are as follows:

 

-Gigabyte ga-990fx gaming mb (same problem with asus m5a97 r2)

-amd fx 8350 OC@4.4ghz@1.42v (same problem even if not overclocked.

-8gb dual channel (2x4gb) hyper x ddr3 1866mhz (same problem with corsair vengeance 1600mhz)

-750w power supply

-amd r3 ssd 240gb

-asus strix gtx970 3.5gb

 

The temps are as followsusing OCCT 1,5 hour:

 

Cpu: max 54 celsius (using corsair h100 aio)

NB: 50 celsius

 

Gpu after furmark:

Max 70 celsius

 

All other games work perfectly smooth except black ops 3 which has some vram leak problems

 

Thank you for any help and for taking the time to read this post

Use afterburner to monitor data when playing crysis. It could be 1 of the cores hitting 100% usage while others stay at low usage.

Thank you for the answer. And if it is what could be done to adress the problem

If your CPU is spiking or is fully loaded, then the only way to address it is to upgrade. You could try overclocking it, but that may not get you very far.

Bullshxt like getting a new system? Your CPU is already at its limit considering the voltage, and there's no way you can make crysis run better on a 8 core CPU (though crysis' multi-core optimization shouldn't be that bad)

[Rackooo]

The only core that is spiking is core 8 at 87%. The thing is ive seen many people on youtube run it perfectly with the same configuration

this chart even show the processor is almost on pair with the i7 3930k and running with an 690gtx the lowest fps is 47. Thats what i dont get. The oc cpu and the 970gtx should outpreform the tests shown in the graph

Yes but that's only representative of what they tested, not what should be going on all the time. If you can figure out how they tested it, you can run it for yourself to verify the results.

i saw videos on youtube runing it no problem on the same specs. and the strange thing is this happens even on the lowest settings. for example i can play gta 5 at max without advanced settings at 58 to 75 fps constant. the lowest ive seen it go is 57 at probably the most busy street with tons of explosions. battlefield 1 runs at ultra settings 80 fps the minimum is 65 (without AA) so not runing cysis even at minimum because of a CPU bootleneck doesnt seem plausible

What's a good cpu to run Crysis 3 on?

Ok so a bit of an update. I have had time to play around with the problem a bit, so i ran the game with the msi afterburner monitoring overlay. A few things i saw were, it uses about 3560mb of ram so that is not the problem, none of the cpu cores exced 80% and the gpu fluctuates between 83-94%. As soon as the framerate drop occurs the cpu usage droops to 30% same goes for the gpu that drops to 25-30% usage. After that it goes straight up again until the drop occurs again. Nor are the gpu or cpu ever stressed to the point that they reach the max temperatures that i see in other games (gpu now maxes at 68 celsius, and cpu at 44 celsius). In crysis 3 the gpu temp reaches max 58 and the cpu max 38, so that makes me believe that the game isnt using the pcs resources

SOLUTION! https://www.youtube.com/watch?v=HTA2OPdnqPM&ab_channel=pcgamingFTW

 

Apparently Nvidia managed to introduce a bug in their drivers, which made Crysis 3 stutter and even have severe framedrops. The solution is to enable Ultra low latency mode in the Nvidia control panel. In this clip you can see, just how much the game stabilizes in the frametime graph in upper right corner, once Ultra low latency is activated. As a side note, setting it to "on" doesn't do the trick, it needs to be set to "ultra"!
