Grimm Quest for the Gatherer's Key is a Hack and Slash Fantasy game with some platforming elements that leans heavily on extremely bloody and satisfying gameplay. Players can explore a huge world that often offers several different routes that lead to accomplishment. Almost every part of it is customizable to taste, not only the graphical aspects but also it's gameplay aspects.

Configuring Graphical Options for Grimm


Please read the special notice for AMD/ATI users in the section below.

Grimm Quest for the Gatherer's Key includes Sikk Mod, a feature filled mod that allows for graphical enhancement beyond the ordinary capabilities of the Doom 3 engine. Because of this the system requirements quickly go up depending on which features you enable or not. The highest quality features like Screen Space Ambient Occlusion, HDR and ambient lighting require a strong computer and video card.

You do not need to have Sikkmod installed to run Grimm!
Grimm also does not change anything in your normal Doom 3 game!

Grimm gives you the option to bypass Sikk Mod completely, you can turn off all advanced features making Grimm run basically like the original Doom 3 does, especially in lower quality modes as well (low, medium). Of course, these quality modes are less immersive than the higher quality modes that offer crisper textures and better lighting.

I have included several configurations that will allow you to quickly set several recommended settings for Grimm in the graphics menu. These options configure many graphical settings for you and will save you 'tinkering time'. The basic options like resolution, texture and quality modes still need to be set from the main menu.

Important
Grimm uses an auto executing configuration file called 'autoexec.cfg' it resides in the root folder of the game. Never edit or delete this file as it contains important settings that are required for Grimm to work properly.

Things that get adjusted automatically depending Quality Setting
The Doom 3 engine knows 4 quality settings: Low, Medium, High and Ultra. There are many differences between these modes and Grimm adds even more functionality to these. Many dynamic aspects are based off these settings. For instance, burning objects only cast light in high and ultra quality modes. All breakables drop movable shards are removed after 4 seconds in Low quality mode and stay for over 14 seconds in Ultra quality mode. Some effects aren't shown at all in Low quality mode. Low and Medium quality modes compress textures and texture size. Overall you can say that in low and medium quality modes many textures look more blurry than in higher quality modes, including some HUD elements and menu elements.

Ambient Lighting
When turned on, the ambient lighting options are controlled by Grimm. You can set your own values in the CVars and they will take effect, but they will reset upon map load. Each hub has it's own distinct ambient colour that translates in these settings.

Screen Space Ambient Occlusion and alpha transparent planes (sprites)
One flaw of this technique is that transparent planes cannot be calculated correctly, this shows in visible edges around some alpha transparent planes. I have found a workaround for this by reversing the plane normals and fooling the engine into still drawing the plane. But this doesn't work always and it's hard manual labour so to say. So you'll see these issues pop up with SSAO enabled. It shows less when HDR is also enabled, so when you enable SSAO and want less artefacts then make sure to enable HDR. You can also play around with the SSAO settings themselves. Grimm defaults to it's recommended settings but you can tweak and adjust as you desire.

Advanced console options for Sikk Mod

For reference I will provide all relevant render cvars and options available from Sikk Mod in Grimm on the next page. For support regarding any of these options, please reply to this tutorial!

SPECIAL NOTICE FOR AMD/ATI USERS

The AMD/ATI Catalyst Control Center AI has known issues with Grimm and SikkMod. These issues can result in garbled screens and other random anomalies. These issues can easily be fixed by turning off Catalyst Control Center AI completely while running Grimm (or Sikkmod and most other graphical enhancements mods for Doom3).

There are many other known issues with the Catalyst Control Center AI so the general recommendation in all of these situations is to turn it off. Remember if you are experiencing the same issues in other games there could be an issue with the card in which case I will always refer to your manufacturer.

1) Open up Catalyst Control Center
2) Under the "Graphics Settings" tab click 3D
3) Click "All Settings"
4) Scroll through the list until you see "Catalyst A.I."
6) Check the "Disable" box.
7) Cick OK.

The AI should now be turned off.

ps: Got to love rogue AI! :)

Try setting the quality to high or ultra.
Do you have any subfolders in the grimm directory, or do you have any other mods installed? Sometimes these files can interfere with Grimm.

i've updated the drivers, when i have a chance i'll try to play the mod again, also i dont have other mods installed, i dont have any subfolders in the mod directory, and i was playing in ultra, so i guess the problem is the drivers.

It's always a pain to figure out these issues. Usually it's drivers, usually it's a setting, usually it's some old mod etc..etc.. But sometimes the issues aren't that obvious. I can help you more in depth if you register an account at this forum: Doom3world.org then you can also give me a screenshot of what's happening and I can ask some more in depth questions.

I am the user called 'BloodRayne' there. You can begin a new thread, or PM me with any issues so we can figure it out.
