I dont know if the laggy video is common on ATI versus the Nvidia users, but if your having sluggish, laggy gameplay then I guess you could try to find the equivalent stuff in your ATI settings. Especially in the inventory and magic screens for example I would see lots of lag on the mouse.

Now, for us NVidia users. I decided to tinker with the ARX 3d settings profile in the Nvidia Control Panel. When I made the following changes, the lag seemed to practically be gone, and the menus stopped feeling wrong as well.

Mind you I wanted to also force things like AA off. So its worth setting these too "just in case". You can tinker later. First see if all these settings actually help at all.

I changed
Antialiasing Mode = Application Controlled
Antialiasing Transparancy = Off
Maximum Pre-rendered frames = 2
Power Management Mode = Prefer maximum performance
Texture Filtering - Anisotropic sample optimization = On
Threaded Optimization = Off
Triple Buffering = On
Vertical Sync = Force on

Anyhow, those helped a lot. Especially in the player menus. I used to get a LOT of chuggy mouse movement when I had the inventory, or spell menus open. Not anymore.

Hope this helps some folks.

Edit: Just as a note. I can also now play fine at 1920x1200, with max visual settings in game and even the menus work fine now.

Edit 2: Cutscenes are no longer super jerky for me either.

Hey Wolfen - great work!

I'd almost given up trying to play this again but you fixed it.

Thanks for the patience and perseverance you obviously had.

Glad it helped some one else. =D

Just a question, where do I find the grafic card Control Panel ?
Im a bit new to this. I did make the changes in game, but the just did the grafick look better ( even that I in my eyes made it worse, I did put LOW on theings I before had on HIGH ).

But I still walk faster then I run ;)

Typically you can just right click on the desktop and you should see "Nvidia Control Panel" on there.

Look for "Manage 3d Settings" in the Nvidia control panel. Then select the "Program Settings" tab on the right pane. From there, find Arx Fatalis in the drop down menu and make the changes you would like to make there.

Ok Thnax, that was easier then I fought ;)

No problem. Hope the tweaks help. =)
