Frequently Asked Questions regarding compatibility, requirements and performance of AtmosFear 3

Q: Is it working with Complete CoP
A: No. But, as Complete CoP is mostly based on Atmosfear 2 and Absolute Texture Packs I recommend unistalling Complete and installing AtmosFear 3 along with Absolute Texture Packs from addons section. Your game will look the same. Or even better as Complete uses obsolete stretched vanilla sky textures and wrong white balance.

Q: Would you merge it with Complete?
No. Period. DIY.

Q: What patch is AtmosFear 3 compatible with?

A: It is recommended to patch the game to 1.6.02. The mod has been created and tested on this patch only.

Q: What DX version is this mod compatible with?
A: AtmosFear should look the same on DX9 and DX10 (Full dynamic lighting). It can be also used with DX8 (Static lighting) but the shadows won't have accurate direction.

Q: Should I uninstall previous versions of AtmosFear before installing AF3?
A: Yes, it is highly recommended to uninstall previous versions of AtmosFear as AF3 uses different config and textures filenames. Keeping previous versions will cause the previous configs and textures to load as well. Even if they not used anymore. It will raise the RAM demand and loading times twice.

Q: How to uninstall previous versions of AtmosFear?
A: Go to menu Start > Cromm Cruac and run Uninstall AtmosFear 2 (recommended). Alternatively you can delete/rename your gamedata folder. If you have had merged AF2 with other mod I recommend to delete/rename gamedata and install the mod with AF3 again.

Q: I can't go pass the license in AF3 setup. The 'Next' button is greyed out.
A: With Vista and W7 it may happen that you can't see radiobuttons to accept the license. Turn off Aero theme temporarily using Classic Windows theme and turn it back on after installing. Alternatively after clicking 'Next' on welcome screen hit Tab then cursor up on the licence screen. You should see 'next' button active.
If nothing helps you can install the mod manually. Copy contents of each dir from 'data' folder: bin->bin (make a backup first), gamedata->gamedata, loading_screens->gamedata, nano_hud->gamedata, textures512(or textures1024)->gamedata\sky

Q: The options screen and the messages are in different language

A: The options and messages should be the same language as your localisation. Anyway, try to copy contents of gamedata\configs\text\*your_language* to gamedata\configs\text\rus (or whatever language they are now).

Q: Is starting a new game necessary?
A: Yes, with AF3 it is REQUIRED to start a new game.

Q: Is loading user_atmosfear.ltx required?
A: From version 3 there is no user_atmosfear.ltx anymore. Correct settings are loaded when a new game is started.

Q: The sky is too dark, the ground is too bright. Why?
A: Go to AtmosFear Options menu > Other options and load default color balance and brightness settings.

Q: The sun rises at west and sets at east, nights are too short, days too long etc.
A: In AF3 the sun has the correct position acording to geographical/astronomical data. It requires replacing the game renderer DLLs with fixed ones. It is done during the installation.

Q: Are the fixed DLLs considered as crack?
A: Not at all! The fixed DLLs merely re-enable the sun position to be configured from the config files. They don't remove any protection. You still need an original game to play.

Q: My render DLLs are missing after uninstall and I can't run the game
A: Copy them back manually from '\bin\dll_backup' folder to '\bin' folder.

Q: Why the weather changes when when reloading saves?
A: It's how the engine works. When you load a save the engine can't set the the same transition between 2 cycles and sets the weather that is at the end of the transition. Let's say it's 9:01am, it's foggy but the next cycle selected is clear. If you save/reload the engine will set clear for 9:00 and clear for 10:00 so you'll see clear weather on 9:01 when it was foggy before save..

Q: Why is the NPP visible north of Pripyat while in real world it is south-east?
A: In S.T.A.L.K.E.R. universe NPP is north of Pripyat according to maps available in Shadow of Chernobyl and Clear Sky.

Q: Why it takes so long now to load save game?
A: The mod adds 140+ sky textures sometimes in high resolution (depends on chosen option). That's why.

Q: Game crashes after installing this mod
A: On systems with less than 2GB of RAM 'Out of memory' problems could occur. Do not install hi-res textures unless you have at least 3GB of RAM and decent GPU.
The same apply to 32 bit systems where xRay engine can allocate maximum 2GB RAM
Other cause can be incompatibility with other mods.

Q: I've got a problem with AtmosFear and other mod
A: AtmosFear needs to be properly merged with other mods.

Q: AtmosFear is included in other mod or compilation and I've got a problem with it
A: Contact the author of the compilation. I don't take any responsibility for unproperly merged AtmosFear.

Q: Why the ground/plants textures look different than those on the screenshots?
A: All screenshots have been taken using Absolute Texture Packs.

Q: What is the performance hit with AtmosFear 3
A: This can vary depending on the machine/system. Some people report increase of framerate of about 10% some report FPS drop.

Q: When using the nightvision during the night I can see ugly square patterns on the sky.
A: They are bitmap compression artifacts. Nightvision screen effector raises the brightness enormously. Especially in dark areas where the compression artifacts appear the most. I did my best to reduce their appearance but unfortunately I can't do anything with the bitmap compression.

Q: Sky textures have discolorated patches especially in gray areas
A: This is because I've used 16bit sky textures to reduce the RAM demand of the mod. 16bit palette replaces some gray colors with slightly purpleish, greenish color equivalents.

Q: Why there are no ultra resolution textures anymore?
A: The only advantages of ultra textures were slightly better looking skyline (with NPP etc.) and slightly sharper stars. The clouds are blurry anyway so there is no reason to expand the skyboxes resolution. And the RAM demand (and loading times) with ultra res were enormous.

Q: Would you release ultra resolution textures later?
A: No. Period.

Q: Where can I find more answers?
A: Read the thread on the official GSC forum
