This hack should work for Crysis Warhead Enthusiast Settings, because it is using the same cryengine 2!
Enable the “Very High” quality setting in Crysis and Crysis Warhead on your dx9 or dx10 compatible hardware without having Vista and DX10 (DirectX 10)!
After building a new PC-rig, I had to try it out with the best PC game on the market today. At least as far as near photorealisticgraphics goes, Crysis. Under Windows XP (DirectX9) you can’t select the “Very High” settings in the graphics menu. These are reserved for Vista (DX10). However I don’t know if this is because of a Vista marketing thing, but the Very High quality can easily be achieved under Windows XP (DX9) , replacing a few textfiles in the Crysis Folder. (CRYSISGameConfigCVarGroups)
This has been known for quite some time. What it does isthat it changes crysis “High” settings to have “Very High” quality. The old version of the hack just changed this. This meant that there was no way of selecting the old “High” setting, because “High” was now “Very High” and the step below was Medium.
My version of the hack changes the “Medium” setting to high quality, and the “Low” setting to medium quality.
You are right, then there is no way of achieving low quality anymore. But if you are interested in “Very High” settings, youare probably not going to want to run that on a machine that only can display low settings…
Here is some further technical explanation:
I did a remake of the Cvar files. Instead of just copying the high settings to  I also renamed old  to , old  to  and removed old 
This way what used to be:
High is Very High
(This is all the candy!)
Medium is High
(What used to be our highest setting is now activated when we choose medium)
Low is Medium
(It doesnt go any lower since there are only 3 steps in XP i had to get rid of low settings alltogether)
Before with the old cVars “hack” if I chose to lower some settings, I actually had to go two steps to medium (from very high) now since meduim corresponds to high it’s only one step in that sense. There will of course be no Low settings, since they are now like the old medium, but I think anyone who uses thisk hack does not need to have anything set at low
Before we had 4 2 1 now we have 4 3 2 Which makes more sense.
Just like the original hack, I didn’t touch the MotionBlur file which is set to 1 (Very High Would be 3)
It seems to work fine, these are screenshots taken at 1280*800 scaled to 50% and auto contrast corrected with Microsoft office image editor to sharpen them a bit.
This is Low (as standard Medium):
This is Medium (as standard High):
This is High (the tweaked mode Very High):
This means that if you install these cvars files, just go back to the menu and select “Medium” settings and everything will be just as it was previously on “High”, consequently setting something to “Low” will correspond to the old “Medium” setting.
I think you get the point
Here is the zip-file with the cvars
Unzip to the folder CRYSISGameConfigCVarGroups
“CRYSIS” represents the install folder for crysis. It might vary. Thx Jonno.
If you think this was helpful, consider buying me a cup of coffee:
Disclaimer: I’ve had one report of losing savegames after changing the cvars files. This makes no sense at all, because the two things don’t have anything remotely to do with eachother. Sometimes updating the game with a PATCH might make you appear you lost your savegames, just see that you load the game with the same profile as before and your savegames will be back. However this hack only changes some graphics card settings and should in no way make you lose your savegames. But of course, you should use common sense when editing gamefiles. If you don’t know what you’re doing don’t mess with it, and buy a console
