Connect failed 1080ti #2

Hi, your product looks promising, tried 1.0.4 beta with blender 3.2, gtx 1080 ti and the latest game-ready 516.94 driver but it doesn't start up, prints this message: ERROR | connect failed. DirectX version, hardware or driver are not compatible. Please check the system console for details. Feel kinda dumb. Do I miss something obvious? Could you tell me where to look for the system console/log and what to do?

According to various hints I googled, the GTX cards do not support DXR 1.1.

blRstr should print more info into Blenders system console. It can be opened with "Window -> Toggle System Console" (https://docs.blender.org/manual/en/latest/advanced/command_line/launch/windows.html#details).

There should be something like: "rstr requires RaytracingTier >= D3D12_RAYTRACING_TIER_1_1" or "rstr requires D3D_FEATURE_LEVEL_12_0 or higher"

Alright, this confirmed. Sadly, DirectX 12.2 dubbed "ultimate" that has dxr tier 1.1 isn't available for 10xx series now. So, rumors about rtx being emulated on older GPUs are far from truth. Even with games, Control is the only one i've seen with DX raytrace feature that works with my rig. To anyone reading this: get an RTX @stkrake , how much will your renderer cost when it's released? Would like to buy along with a new GPU :) Is there a viable possibilty of you making this work with the dxr version that GTX series support? A lot of people will still use it for years in the future because of its price and power except raytrace cores

Good news: It will cost nothing, because it will become open source :smiley: Bad news: I dont know when it will be ready. The code needs cleanup and I dont have enough time atm :worried:

Even if it would be possible (never thought about it), I would not have the time for it.
