Test 2 (driver VRAM paging test)

A proof-of-concept application rendering 3D graphics using a Radeon HD 4000 series graphics card on AmigaOS 4.x. This test is designed to test the Radeon HD driver’s VRAM paging, to make sure that it works properly (which it does). The test application renders a simple looping 3d animation that overfills the graphics card’s VRAM with textures and vertex buffers. As a result, the driver has to swap buffers in and out of VRAM. As you can see, it handles this just fine, albeit with the expected drop in performance (the momentary pauses that occasionally occur in the video). For more information, see NOTE: To see the animation without VRAM paging, check out the following video: Thanks to hostcove () for helping to record the video at high quality (without pointing a camera at the screen).
