Crysis 3 potential fix for low GPU usage

Hello everyone,

 

I made an account to comment on this particular issue. I made my own investigations, since it was really frustrating to not be able to play this game in good conditions.

1: You have noticed this already, but the AMD cards are perfectly capable in the game, the problem comes from specific locations or scenes where the GPU usage drops very low.

The issue has already been discussed here, but I wanted to add what I found.

Crysis 3 low FPS drops & low GPU utilization with RX 480 This thread includes several videos of the issue being reproduced on AMD GPUs, and not being there on much less powerfull Nvidia GPUs

 

2: I have managed to replicate this issue in another game, Kingdom Come Deliverance. This is particularly interesting as the game also runs on CryEngine (a more recent version). And in fact it is possible to solve it. Look at this video Kingdom Come Deliverance - r_BatchType perfomance - YouTube 

 

The issues are very similar, good FPS until you look at a certain scene, then GPU usage drops to a low level. 

Sadly I have very little knowledge about what this setting exactly does, but it does fix the performance, I also tried it myself.

 

I have no idea if it fixable for Crysis 3, I fear that it is not. I have tried everything, but I have not managed to find a similar console command on Crysis 3, perhaps this version of the engine didn't support it yet. 

Since I am new on this forum, let me know if I posted on the right place.

 

Hopefully someones reads this.

Did you try searching CryEngine documentation or contacting CryTek Technical Support?
Thanks.

Re: Crysis 3 potential fix for low GPU usage

Hello, the "fix" presented in the Kindom Come Deliverance video is maybe a bit more explained here 

RBATCHTYPE - CryAutoGen - Documentation 

I haven't tried to contact the CryTek Technical Support yet. I was exposing my reasoning behind what I observed myself and from others. I have doubts that AMD or CryTek wouldn't know that...You never know

Thanks.

I will take a look.
I think CryTek CryEngine Support might be worth a try. They have responded with useful information for me in the past.

I will contact them  if you want but perhaps you are the better person to do it?
I have been more of a "verify the problem monkey" for you.

I have seen rumours of new versions of Crysis Series with improved Graphics so they *might* be interested to look at the AMD Performance problem, even if AMD are not:

Crytek is hinting at a remastered version of Crysis (updated) 

Hope you and your family are o.k. in this "Lockdown" situation.
Take care.

Re: Crysis 3 potential fix for low GPU usage

I have all of the Crysis games in Origin and I have played them a while ago. But I have not tried them on the RX 480 8GB yet. I am still downloading a boatload of game updates on Steam etc.

I can test all of them as I have Crysis, Crysis 2, Warhead and Crysis 3

Re: Crysis 3 potential fix for low GPU usage

I know this is like 2 months old at this point but I "tried" to play through Crysis 1 and 3 again because they were re-released on Steam and figured they were now the same as the updated Origin versions and it turns out Crysis 1 is not, Crysis 3 IS but it still requires Origin to run which is obnoxious. From what I've been reading only the 5000 series and Vega cards are having major performance issues, the RX 400 and 500 series is still fine. But, I have a 5700XT and the performance in all of the Crysis games is atrocious. I go from like 160FPS solid on my 1440p 144Hz monitor with nearly all settings maxed to constant FPS hiccups, stuttering and straight FPS drops with low GPU and CPU utilization for seemingly no reason in Crysis 1, in Crysis 3 it seems to be looking in certain areas causes it, I also get layered texture issues where they'll start to disappear the closer I am to them, such as posters on buildings in Crysis 3 and some ground effects and such in Crysis 1. I don't remember having that issue on my RX 580 or my R9 290 or my HD 6870. I've tried the lowest settings, even modified to be even lower than the lowest with cvar editors and it makes no difference.

It's also worth noting this mainly happens with Windows 10, people running Vega on Windows 7 or 8 don't have any problems so it could also be a Windows 10 problem.

Re: Crysis 3 potential fix for low GPU usage

Crysis has 32-bit and 64-bit versions. The 32-bit does not work but manually loading the 64-bit version does work.

Re: Crysis 3 potential fix for low GPU usage

I am forcibly running the x64 version with the AMD 3DNow CPU fix, still has major performance issues on newer AMD cards. My older cards played it perfectly.

Re: Crysis 3 potential fix for low GPU usage

Game works fine on my RX 480 8GB and also on my GTX 1060 3GB so I wonder of your setup is mangled.

Get DDU and clean up the video drivers and try 20.5.1 clean

Re: Crysis 3 potential fix for low GPU usage

I am on the most current and the drivers are clean, I have a master list of all the files used by the AMD drivers and make sure they're gone after using the AMD Cleanup utility and DDU and they were indeed gone. I said that only Vega and 5000 series are affected in my first post so your 480 and 1060 won't be affected. Kingdom Come has the same issue but there's a cvar that fixes it, that cvar doesn't exist in C1-3 though so definitely an issue with CryEngine and AMD.
