In actual implementations with AMD Mantle and Apple's Metal on desktop-class GPUs there are mixed performance gains (sometimes faster than OpenGL, but also sometimes slower). On much more powerful desktop GPUs the real-world improvements of such an approach is less clear. This approach is helpful where call overhead is significant, and on less-powerful devices such as mobile devices.
Cant run doom 3 demo drivers#
The curse is that the driver has fewer optimizations built in, and future drivers can't contain optimizations for games. The blessing is that application developers can gain better performance in some cases, as there is less hardware abstraction and they can gain more control over execution of graphics operations. The optimizations are pushed to the application developer to do. Vulkan drivers are easier because they do less and contain fewer optimizations. The game is very reminiscent of previous Doom titles and the action is non-stop.Ĭorrect.
Cant run doom 3 demo 1080p#
Note that the game was running on a projector at a resolution of 1080p with all in-game image quality options set to their maximum values. With the framerate cap removed, the framerate jumps into triple digit territory and bounces between 120 and 170 frames per second, give or take. A few minutes in, however, at about the :53 second mark.the rep from id says, "We're going to uncap the framerate and see what Vulkan and Pascal can do". In the initial part of the demo, the game is running smoothly, but its frame rate is capped at 60 frames per second. the first public demonstration of the game using both NVIDIA's new flagship and the next-gen API, which is a low-overhead, cross-platform graphics and compute API akin to DirectX 12 and AMD's Mantle. MojoKid shares a video showing the upcoming Doom game on NVIDIA's new GeForce GTX 1080 graphics card using the Vulkan API, quoting this report from HotHardware:Īt a private briefing with NVIDIA, representatives from id software came out on stage to show off the upcoming game.
