Bastion of Chaos - Low spec version is up!

Recommended Posts

It's good to see people trying this map out even if slaughter isn't their thing. Highly recommend starting out on HNTR or HMP and leaving UV for a 2nd playthrough.

Now that I think about it, is there a way to change the draw distance or distance view in GZDoom/LZDoom? Because i think that could drop less fps.

No.  IIRC, GZDoom very deliberately does not include that - I believe the Blade of Agony guys wanted to add it but it was decided it wasn't in keeping with the port.

@Turin Turambar while map geometry is one of the main factors on fps for doom, gpu draining elements like dynamic lights and static portals definitely affect fps. Removal of half the dynamic lights had a large impact on fps and if you run the map with lights.pk3 (which attaches lights to all projectiles) then the big fight at the end will have around a 50% fps drop. Turning dyn lights off at this point will cause the fps to bounce back. Your screenshots show a 37.5% increase in fps from the full to low spec version and the only thing different in that area is the dynamic light count.
And if gpu didn't matter then I wouldn't of had an fps jump when I upgraded my graphics card. 

 

Just for curiosity, what's your fps in that place (it's where you pick up the chaingun) with your computer?

I restarted my previous playthrough, to use the low Spec version.

 

The art and level design is visually impressive, of course. The gameplay is also good, there is a nice variety of slaughter situations. The flow is less good, sometimes it isn't very clear to the player where to go next, or what is a switch, or even one case, I couldn't see a key (red key) because all the damn corpses lol.

 

Coming back to performance, even in the Low Spec version still has some bad places. Example:

My 0.02$, but no Doom level should cause the fps to fall to 21-23 fps, in a fairly powerful modern computer.

 

Are people playing like this? or there is a trick or another sourceport I don't know?

Well for a start you appear to be using a mod. There are a shit ton of addtional gibs in that shot so I'm gonna say that's what the issue is as I'm getting almost triple your fps on the high spec version.

Mainly, the only visual mod I have is SmoothDoom HiRes, I couldn't imagine it would affect performance so much, but I will do tests.

Ok, sorry for the bother, but at least I'm discovering interesting stuff. Yes, turning off the extra decoration sprites and gore in SmoothDoom improved things. I guess the performance hit is small in normal levels, but it scales badly in levels with thousands enemies.

And even more interesting... I was losing 10 fps from Vulkan, even in the normal, no-Low Spec version. WTF! I thought Vulkan performed better. I switched to Vulkan one year ago after doing tests in a level (I still remember it, it was Brigandine) and I had clearly better framerate with Vulkan.

I guess there is a cutoff point, and levels that surpass some size/complexity actually perform better in OpenGL than in Vulkan.

I finished the level yesterday night. The end was suitably epic, with the last fights being even grander and more intense. In the final moments I had already spent all the big power ups and just charged like crazy towards the front (as a new group of CDs had spawned behind me), thanks god that was the correct choice, as the exit was there, I entered it without even knowing what I was doing lol.
