      Server Move   09/13/18

      I (Dries007) have recently taken over as main developer and server admin. This involved moving servers to reduce cost. It's likely there will be some more downtime in the future but most  things should be sorted by now. This forum is in dire need of replacement as the software is quite old and can't be easily updated. If you wish to discuss or stay updated, join our discord: https://invite.gg/terrafirmacraft. The forum will remain available to read, but will be locked in the future, when a new system is setup. The forum and wiki are now ad free. If you'd like to contribute to keeping it that way, you can do so via paypal or patreon.

Does Dynamic Lighting run well for anyone at all...?

8 posts in this topic

I see multiple TFC modpacks having this mod in their recommended list. I have also seen streamers (both TFC and regular modded Minecraft) use this mod, and it always looks so cool. However, whenever I install it, my performance simply disintegrates. There's really no other word for it than that.

 

The thing is: my computer isn't exactly weak. I have a desktop Haswell i5, overclocked to 4x4.20 GHz. There's 16 GB RAM available for the taking. And my videocard can run games like FF XIV at maximum settings just fine, so I doubt Minecraft is going to struggle on it... In fact, when I boot up a new Terrafirmacraft world, and let all the chunks load, my framerate will sit snugly pressed against the 120 FPS cap defined in the video options, even with maximum view distance. I didn't check how high it would go uncapped. (Yes, I do have Fastcraft installed.)

 

But as soon as I select a torch in my hotbar, boom, I'm down to 40 FPS. Okay, I have played Minecraft on weaker systems in the past, capped to 30 FPS, so I could deal with it. But it's not just the framerate. My game stutters in the rhythm of Dynamic Lighting's update interval. Each cycle, defaulting to once per second, the screen will freeze for a tiny fraction of the blink of an eye and then jump forwards to catch up. It's utterly, gruesomely jarring.

 

This really surprises me, because apparently the mod must run more smoothly like that for someone, right? Nobody in their right mind would play like that, much less think it a good idea to distribute it in a modpack to random people with god knows what hardware. And none of the streamers I have watched seemed to have that microstutter issue either. Is that something only I am experiencing, for some arcane reason? o_O;

Keep in mind that when you watch a stream, you aren't seeing everything that they do. Those streams are usually only 30 FPS, with the rare streamer that has fantastic internet doing 60 FPS. It's much more likely that those streamers are experiencing the exact same issue as you, but the timing is such that by the time it goes through their streaming client, through twitch's buffers, and to your monitor, those frames with the stutter just don't appear.

It will always cause some issues with performance, but with a decent system it should be fine.

Have you tried the JVM arguements from the TFC wiki? Search performance optimization I believe.

@Kittychanley: Considering how extremely noticable it is on my system, I'm not fully convinced that the streaming interface would hide all of it so reliably... but well, I don't exactly have proof to the contrary, either.

 

@Busan: I looked up and tried the Java arguments, which made no noticable difference whatsoever. Still, thanks for trying to help.

 

 

It's a crying shame, but I'll be giving this mod the boot :( The more I look at it, the more I consider it flat-out unplayable (and this is coming from someone who will accept 30FPS without complaint).

 

Back to tweaking configs I go...

I see same performance issues with this mod. Best rely on the same effect provided by some shader packs like SEUS.

I have to agree with Terex.

 

(Shaders mod + SEUS) you'll have better results.

 

Good luck!

I've always shied away from shader packs due to how much inconsistency they introduce. I think I've tried them in 1.5, in 1.6 and in 1.7, and every time I saw the exact same issues: sunlight appearing in caves deep underground, landscape shadows disappearing when the player breaks line of sight with the sun, water becoming all but invisible when placed out of sunlight, and a lot of other small irksome things that nobody ever shows you in screenshot and promo videos but that you come across during actual gameplay all the time... Yes, 90% of the game looks better, but the remaining 10% is problematic and, to humor a certain phrase, breaks my immersion. Minecraft's default look my be low-fi, but at least it doesn't remind me every minute that I'm playing a videogame with a not fully working mod.

 

I mean, perhaps you can fix those things. But I've tentatively toyed with some of the settings, and nothing I did made a difference. And every single one of the 10+ premade shader config packs I downloaded showed those exact same issues, too... persistently across many different mod and Minecraft versions. So it's certainly not giving me the impression that it's fixable.

The latest version of SEUS 10.2 preview 1 still shows the sun in caves during sunrise and sunset. But otherwise no other jarring visual effects. I think it's acceptable.
