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.

Sorry not nearly enough pesos to buy every make and model of card out there.

Re: Crysis 3 potential fix for low GPU usage

I recently re-played Crysis 3 and can confirm that in some scenes, the GPU usage drops inexplicably.  From 100% down to ~30%.  Especially evident in the opening level.  RX 5700XT.

Re: Crysis 3 potential fix for low GPU usage

I sent an AMD report 8 months ago ... and wrote to the email ... even shot a video.

By the way, there is a similar problem with Metro Exodus on Directix 12.

In the apex of legends on the new map, too, someone complained ...

I think amd will never fix it. 

PS: AMD - constant "surprises". I put together a completely red assembly. I fussed with her for a year as much as I didn't bother with intel for 9 years.

Re: Crysis 3 potential fix for low GPU usage

I'd just like to mention that this week I upgraded to a Ryzen 7 3700X and ASUS Prime Pro X570 mobo and the issue is gone. My FPS has sky rocketed to 200+FPS highs with a mix of mostly high settings and never drops below 100FPS. Could be command over flow in the GPU pipeline when the data is sent through the CPU to the GPU as that was the only change I made to my system and the 3700X's single core IPC is massivle higher than the FX-8370 I was running before. Still the same 5700XT and drivers. I didn't even reinstall Windows 10, I just slapped the components in and let Windows 10 configure itself and installed the chipset driver package for AM4 boards.

I use an R5 3600 on a MSI X570-A PRO and 32GB of memory. RTX 2080 plays all games. My RX 480 plays Crysis 3 fine, i played it for a while before I updated my BIOS and installed my RTX 2080.

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"!

Re: Crysis 3 potential fix for low GPU usage

@marcolopesthis does not work on AMD Radeon, since it is a different bug.

@hardcoregames_Crysis 3 runs fine on Windows 7, the issue is on Windows 10 with Radeon in certain scenes where GPU usage and CPU usage drops below 50% and the FPS stays consistently very low.

A good example is in the first level where you get to the steam rooms with large spinning cylinders the FPS tanks hard with very low utilization and CPU grunt barely makes a difference in these scenes.

Testing on Windows 10 with FX 8350 gave me 20FPS in that scene and then with an i5 8400 gave me 30FPS in the same scene with RX 480, but then testing on pre- RX 480 supported drivers and an i5 4670k system with Windows Home 64-bit gave me 50FPS and 100%GPU utilization in the same scene.

Other Cryengine games that perform horrible on Radeon solutions is Sniper Ghost Warrior 3 & Contracts.

Re: Crysis 3 potential fix for low GPU usage

After seeing this problem, I researched and I hope this fixes it for you and also try it for the other games you listed that have bad framerate drops. Please post here or make a new post with the problem and a fix for other games if you can.

Games based on CryEngine have decreased performance on Windows 10 vs 7 on AMD cards[13]. Consider using Windows 7 along with TimerTool set to 0.5ms for the best performance[14] (also on Windows 8). Vega series GPUs also perform worse than RX series on Windows 10 in CryEngine games in comparison to Windows 7[15].

On RX 6700 XT with Adrenalin 21.5.2 or 21.6.1, run RivaTuner Statistic Server and set the framerate limit to 200, this allows it to run fast and not drop into the 40's.

You can disable the show own statistics for Riva Tuner to not show the fps counter.

In Adrenalin, enable radeon enhanced sync.

Edit the C:\Users\username\Saved Games\Crysis3\game.cfg file and add r_BatchType = 1 and then set it to read only.

In the Crysis 3 settings disable vsync.

You can set all settings very high, high anisitropic 16 and AA, it should run at over 100 fps most of the time.

System: B550 5800X 32GB RX 6700 XT 1 TB SSD Win 10 Latest as of 6-21

Re: Crysis 3 potential fix for low GPU usage

Hi @amdman 

Thank you for your efforts in putting together those troubleshooting steps, but like I said the reason I know the problem is on Windows 10 is because I actually reverted to Windows 7 at the time to confirm that it was working much better on Windows 7, which is how I ended up starting this post: https://community.amd.com/t5/opengl-vulkan/crysis-3-low-fps-drops-low-gpu-utilization-with-rx-480/td...

I can unfortunately not just revert to Windows 7 again, because I have too much important files on my computer and is also not an acceptable solution since Windows 7 is not supported anymore.

In addition, tried the r_BatchType = 1 and it does not seem to exist in Crysis 3.

Kind regards

Hello hitbm47,

The information about Win 7 was for additional information to try if the fixes for Win 10 aren't the best for you. It's there for troubleshooting purposes.

r_BatchType = 1 is able to be edited in the game.cfg, if it's not there add it and you have to set the file to read only through Win 10 or it will ignore the value, you have to force it. I am not sure if this helps as I tried many different things to find a fix, so this is optional.

This fix may work for all AMD cards for example RX 480, RX 580, Vega, etc. I have not tried it yet on them, I can report that it works perfect on my RX 6700 XT system and I hope you can get it working, Crysis 3 is still an amazing game and with these fixes it runs excellently.

Update: By using the RivaTuner fixes and turning the AA to 4X and AF to 4X on a RX 580 4 GB and 4770K I am getting 45 fps where it used to go to 16, it is mostly over 60 fps.
