I’ve been able to run The Witcher 2: Assassins of Kings pretty well on my PC (after some graphical tweaks), but some players are having immense trouble. A patch is coming to fix it next week, but if you can’t wait to play something you just spent your hard-earned money on (how impatient!), CD Projekt has some fixes for you.
PC gaming, lads. PC gaming.
Check out the full list of fixes tomorrow.
Difficulties with activation code
There have been quite a few instances that involved entering the number zero (0); you should use the capital letter “o” (O). Also there have been cases where the number one (1), the lower-case letter “el” (l) and the capital letter “eye” (I) have been mixed up. Please try all possible permutations.
CRC Errors when installing the game
Please make sure that any antivirus software is disabled during the installation process.
It’s possible that your DVD drive is not compatible with DVD9 standard. Please manually copy the files to your HDD and try to install the game from there, with antivirus software disabled.
If this doesn’t work, please try and install the game on another machine – also trying to copy the files manually and disabling any antivirus software.
If the above does not help and the DVD disc is in fact damaged, please ask for a refund at the store where bought the game. If this is not satisfactory, please contact us at help2start@thewitcher.com
Game doesn’t start, goes back to launcher
Turn all settings to Application-Controlled in the Catalyst Control Center.
Disable the second GPU from Crossfire configurations until ATI officially adds support for The Witcher 2 in Catalyst drivers.
Try running the game in windowed mode.
Run the game with horizontal resolution no higher than than 1920, and set the desktop to the same resolution as the game.
Ensure that the game was installed with administrator privileges – Windows UAC settings set to minimum or setup.exe from DVD opened with privileges.
Also: Go to User Account Control Settings.
Type in UAC, or go to the System and Security applet.
Click on the “Change User Account Control Settings” link.
(You can also type in this command from the Run menu: C:\Windows\System32\UserAccountControlSettings.exe)
To turn off UAC, move the slider to the Never Notify position, and then click OK. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
Poor performance on a high-end GPU
Please install the latest drivers for your graphic card, and for nVidia cards, uninstall 3D Vision. If you are experiencing low efficiency, please make sure you have disabled UberSampling in the game’s graphic configuration in the Launcher. If you have an nVidia graphics card, please update your driver to the 275.27 beta as of May 17th.
As for ATI users
Install latest drivers ATI Hotfix.
Disable anisothropic filter, antialiasing and adaptive antialiasing and Catalyst A.I.; this can be done in the CCC panel.
Try running the game in windowed mode.
For dual cards linked into crossfire, turn off one of the cards or use the Dirt 2 profile.
AMD/ATI plans to release hotfix drivers dedicated to The Witcher 2. They will resolve problems with game’s efficiency for crossfire users. This information will appear on: http://support.amd.com/us/Pages/Catalyst-Hotfixes.aspx”
