[0.15.0] FPS issues with High Resolution steam engines

[-Deano]

Loading a small test world on for doing some of the new 0.15 stuff.

I was testing how many of the new boilers work off of a single pump. When on the normal sprite resolution, my game easily sticks at 60fps.
When loading at High sprite resolution it brings my entire system to a crawl, barely managing 15fps.

I don't know whether it's just me with terrible performance but I would assume that I should get more than 15fps (My setup is fairly decent).
I have attached a DxDiag result for reference.

If all you change is the sprite resolution and performance drops that means your system can't handle the increased resolution. that's not a but bug hardware that isn't powerful enough (which is why it's an optional option).

GTX 970 with 4 GB dedicated vram should be more than enough.

Oh, do you see all those boilers and steam engines on screen at the same time? Smoke rendering is terrible performance hog and it can bring the best GPUs to their knees. We will look into that in the future. Should be fine if you don't unzoom so much in areas with lot of smoke or if you disable smoke rendering in graphics options.

Just coming to confirm that smoke is causing significant FPS decrease with only 40 steam engines. I have high resolution sprites, but after i disable smoke it's well at 60 fps. Also burning a big forest down can bring it down to 20 fps.

My recommendation is to turn off clouds and smoke. It does not add anything to the game and smoke is actually a visual nuisance to me.

There, I already improved your video performance by 50% ! You can also turn off shadows..

Does smoke still causes performance issues for you in 0.15.11?

160 steam engines on same screen and cloud effects on, 60/60 fps/ups while zoomed out to max.
