Unreal Tournament Community SDK is an open source engine fork of the Unreal Engine 1.x with a modern development framework for Unreal Tournament. A thousand delays later we hit rock bottom and infinite possibilites at the same time with this community-propelled engine fork for one of the greatest 3D games of all time. We will never forget nor forgive what Epic Games did on the 14th December 2022.
The Extension Pack will contain many Tech Demos where you can play and test around everything. In this picture you see, how the Tech Demo for Environment Maps could look like (It's not final however). You can change several settings like the displayed Mesh, the Environment Map, it's Opacity, the Lighting and so on. The Tech Demo System also supports finding hardware settings which will be displayed on the upper left of the screen. Depending on which graphics hardware you have the Tech Demo System places different logos of the hardware and graphics drivers/API you are using.
So if you are using an Aegia PhysX Demo, and then you switch to Hardware mode and are using an Nvidia Card, you will get the Nvidia logo instead?
