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