Fix for low FPS on all graphics settings?

[Chapnasty]

Running the game on Windows 10 at 1920x1080 with a 7700k, 16GB RAM, RX580 8GB graphics. It was a new PC build about 3 months ago - new SSD so did a fresh install at that time.

Any pointers are appreciated, but I understand this game is very poorly optimized.

I'm thinking it's because the Radeon and there's nothing I can do about it. I get about 25 FPS on all graphics settings (Low - Ultra) with uber sampling off across each. Lowered the res to 1280x720 did give me a 5 FPS gain which got me to 30 FPS in some places. Here's what I've tried so far:

• Run everything as admin (toggled admin on steam to try that too)
  
• Turned off AA
  
• Turned on AF in Radeon Settings
  
• Reset the game settings in Radeon Settings
  
• Ran the Witcher 2 Tweaker from nexusmods - upped the texture memory budget a couple times up to 2048.
  
• Made the User.ini read only after making changes (yes the one in Users\me\Documents etc.)
  
• Turned off Windows Defender services (not likely the culprit, but found while searching)
  
• Installed the game in GOG Galaxy

EDIT: This is now fixed. My specific problem in Windows was either a bug with Crimson Relive 17.7.2 or just a bug installing it on my PC. Here's how I fixed it:

• Ran the AMD Clean Uninstall Utility - http://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx
  
• Downloaded and ran the AMD Minimal Setup, which is 17.8.2 - http://support.amd.com/en-us/download/desktop?os=Windows%2010%20-%2064
  
• When the Radeon Settings app launched, I chose Custom Install (Express Install kept failing) and then chose the Clean Install option

There were many reboots in this process but at the end everything worked fine and am getting the 100+FPS on high settings.

In Start go to Choose a power plan and set it to High performance. Maybe that might help.

This didn't have any effect either. I actually ended up setting up dual booting Ubuntu on a second hard drive, and after installing the AMD drivers (and upping the Texture Memory Budget to 2048 in the User.ini) I'm getting 100+ FPS on high settings.

I opened a support ticket on GOG for the issues on Windows, but they just keep telling me to try things I already said I tried when I opened the ticket.

I'm sorry, I happen to have similar problem too. Every settings from low to ultra is just the same, full of stuttering. It's not lagging/slowing per se, in some points I have nice FPS. But certainly when you move around the area, go to city, or rotating camera (even with motion blur turned off), these stutters always came to me.

I play on the recent ROG Strix Notebook, Asus GL553VD with specs:

Core i7-7700HQ
NVidia Geforce GTX 1050 4GB GDDR5
8GB RAM
Running on Windows 10 Home 64-bit, res. 1280x720

I've searched about the stutter fix like from this:
https://pcgamingwiki.com/wiki/The_Witcher_2:_Assassins_of_Kings#Continued_Stuttering_During_Gameplay
or this:
https://www.reddit.com/r/witcher/comments/13path/witcher_2_stuttering_fix/

which overall making me to set the framerate limit (or something) to 1 or 2, and limiting the FPS to 60Hz. But in practice it didn't turn out giving me any siginificant difference.

So for anyone in the know, may I ask how to optimize this game for my specs?
