Possible future suport for older GPU`s? GTX 980? #70
Comments
Sadly this isn't possible because older gpus like the gtx 980 don't have driver support for the VK_KHR_ray_tracing_pipeline extension that this mod uses. The list on gpuinfo has all of the gpus that report driver support for VK_KHR_raytracing_pipeline and out of these some older ones including gtx 1000 series don't have full driver support and aren't capable of running the mod. |
Clear answer. Thanks And - amazing job with that mod :) |
It is possible to run some kind of fallback (at least on Pascal GPUs), but it needs to be implemented on a per-application basis in Vulkan. Unlike Direct3D 12, there is no driver-level fallback provided. This is how Quake 2 RTX can run on non-RTX GPUs despite its name 🙂 (slowly, but playable at low settings on GTX 1080/1080 Ti) Edit: For those looking to run PrBoom+ RT on a non-raytracing-capable GPU, download the 1.0.7 prerelease and replace RaytracedGL1.dll with the one linked here: #12 (comment) It will be slow as emulating raytracing functionality using compute shaders is much slower than using dedicated RT units. Stick to a low resolution (ideally 4:3) and consider leaving the framerate cap to the vanilla 35 FPS. |
As in title..
As a owner of wonderful ROG G751 with Maxwell gtx 980m i was wondering will there be ever possible to run that piece of code..
Can you clarify once and definly?
Take care, great job !
