Nvidia's Medusa on Radeon HD 4850 and 4870
The Nvidia tech demo Medusa, which was designed to show of the advantages of the Geforce GTX 280 and 260, is, due to a patch of tommti-systems.de, running on Radeon DX 10 cards.
With their launch demos, Nvidia and AMD usually show off their latest technologies, in order to advertise their graphics cards. Often those demos are not running on the competitor's hardware. In the past this often was because of the OpenGL API of the Nvidia demos, which allows every producer to make his own adjustments. But since the DX 10 era both companies use the Microsoft API and therefore there shouldn't be any problems with the compatibility - but there are other stumbling blocks: Medusa for example has an integrated query that checks if there is an Nvidia card installed for real.
Thomas Bruckschlegel of www.tommti-systems.de, in his capacity as the developer of ShaderMark 1 and 2, now released a patch that disables this query - you only need a nvcpl.dll file that is part of the more recent Nvidia drivers.
On www.nzone.com you can find the 240 MByte sized download of Nvidia's Medusa demo, www.tommti-systems.de holds the 32 Kbyte small patch. In addition you need the nvcpl.dll file of a current Nvidia driver - which is available at Nvidia or right here, for registered users. In our test the demo ran both with and without the file though.
