[TPU] Intel Launches Free Open Image Denoise Library for Ray-tracing

Quote:
Intel today launched a free Open Image Denoise (OIDN) library for ray-tracing.

Governed by the Apache 2.0 license, OIDN is part of Intel Rendering framework. From the looks of it, the library is CPU-based, and leverages 64-bit x86 CPU (scaling with multi-core and exotic instruction-sets), to de-noise images. Intel says OIDN works on any device with a 64-bit x86 processor (with at least SSE4.2 instruction-set), although it can take advantage of AVX2 and AVX-512 to speed things up by an order of magnitude.

It will be interesting to see the performance and how a HEDT CPU can help in games vs a lower core count mainstream CPU.

It's intriguing, but still not enough to make me interested in ray-tracing yet. Maybe in a few years when enabling ray tracing doesn't tank your fps by 50%

Not anytime soon, every single method that's been released has been a hybrid ray tracing method: OptiX, DxR, Embree, Radeon Rays and PowerVR Ray Tracing. If anything we'll begin to see more objects ray traced as hardware evolves and the frames will keep tanking depending on how much of the game you want to see ray traced.

Which makes lots of sense because the cost of ray tracing every part of a scene far outweighs the benefits.

I'd be fine with a 50% hit as long as the game actually looked much better as a result. In some cases a 50% hit can still be well over 60fps average so if you use that with VRR you'd still get great game play in story driven games.

Raytracing adds a new level of realism to VR, but unfortunately VR as is already burns through your power. So I guess I'm eagerly anticipating when these things become more efficient at least so we can converge on using it regularly sooner.

I'd reckon that Intel is releasing this library because their new cards will be out soon (within a year or so).

I proudly oppose all legislation to destroy our freedoms and support anything to protect our privacy online and off.
Hope I've added something to the conversation!
