Edit: Cheers for the views and responses. FWIW I also re-Lightmapped the scene with slightly higher settings and set Lightmass to 100 bounces. I’m still blown away by what UE4 in 4K looks like and as 4K becomes the mainstream, and as VR moves to 4K… Scary stuff!
Hi, thanks a lot. My PC laptop only runs at 1920x1080p (I check/watch the 4K video on my Macbook Pro 15" switched to native 4K res). So when rendering frame-by-frame it was like 1 or 2 fps, which I imagine will be the realtime framerate if I hooked up my laptop to a 4K screen!
Cheers… Actually I kept TXAA on but because the 1080p version is basically a downscaled version of the 4K render, the 1080p is kinda like TXAA with lots of super sampling/ over sampling. I find even rendering at 1080p direct, with Screen Percentage 150% or 200% in combination with TXAA, one gets the right amount of antialiasing and crispness.
Yes, looks like your CPU is holding you up. Also, are you using an SSD?
I’m actually not having too serious CPU-side issues with my PC laptop (mobile Ivy Bridge i7 Quad). Even the Infiltrator demo, loading it from scratch, compiling shaders, etc, to be honest has been quite reasonable. On my MacBook Pro (Haswell mobile i7 Quad) it actually gives similar performance. Intel Ivy Bridge and Haswell are pretty solid overall, they’ve done impressive stuff since the Core 1 and Core 2 days.
Currently a Skylake i5 or i7 with Nvidia 970 overclocked or 980 Ti will give you the speed you need. However, indeed Skylake reviews have been lukewarm so if you have the budget a six-core Haswell-E with Nvidia 980 Ti will be ideal.
If your budget is constrained, I would still prioritise the Nvidia 980 Ti since that’s a GM200 GPU and give you all the overhead you need for 2K, 4K, GPU particles, VXGI, etc. With an Nvidia 980 Ti any suitable i5 or i7 unlocked Haswell will do the job, and it will be easy to pick the right Haswell motherboard and RAM.
Overall for a new rig a 6-core Haswell-E with Nvidia 980Ti and DDR4 would be sweet. 8-core Haswell-E might be overkill.
I might skip Skylake totally and wait for the next round if I don’t get a Haswell-E.
Edit: FWIW here is “Matinee” zero-bake VXGI in 4K 60FPS using TXAA and the same techniques for rendering “Infiltrator”. TXAA at 4K seems to give beautiful results and downscaling to 2K and 1080p looks very nice, I believe, in terms of softness and crispness. I wish I had a 980 Ti to truly run this at 4K 60FPS ~realtime~:

Thanks for the hardware tips, I appreciate it. Torn with spending £500 on a 980Ti knowing Pascal is on it’s way (and so much more powerful). Maybe I’ll upgrade the rest of the rig first and see what perf I’m getting (with my r290). Would like to switch over to NVidia again for the Gameworks features and better stability. I’m using a Samsung EVO 840 SSD for the two UE4 folders recommended (https://wiki.unrealengine/Boost_Compile_Times) via the junctioning MKLINK functionality. I have the entire Infiltrator project on the SSD as well. I hoped doing this would decrease the streaming and compile times. I also edited BaseScalability.ini to change all texture quality levels to r.Streaming.PoolSize=1500 as someone suggested. I’m not getting streaming happen as much as before (if at all).
Speed isn’t too bad flying around Infiltrator now but I am getting random crashes. Also I’m noticing strange behaviour like selecting an object and hitting undo causes quite a long delay (30 seconds plus sometimes). It’s like the entire Outliner has to re-sort itself (it starts scrolling through it). In general it seems quite strange there’s no folders being used and I wondered if anyone knows why this is the case? I’m going through it now and adding everything to relevant folders / housekeeping
