All things Voxel mods and the bloated lag donkey

[SatanicSanta]

With Voxel mods: SUPER LOW
With Voxel and Optifine: Around 10-15fps
Without Voxel and with Optifine: About 25fps
With Reis and Optifine: 20-30fps
With Reis and no Optifine: 15-20fps
Vanilla: about 20fps
Vanilla with Reis: About 20fps
Vanilla with Reis and Optifine: 20-35fps

I always check for Voxelmods when a modpack update comes around. They don't add anything useful that Reis can't, and just make my framerate low.

Edit: Also, the key to show chunk borders is the same as a Voxel mod, and pops up whenever I want to see chunk borders. Voxelmods get a "booooooooooooooooooooooooo"

The human eye perceives movement and light (sort of) logarithmic scale. It’s more of a 'feel' than 'see' at higher framerates. Most can 'see' the difference at the lower end such as between 15 to 30. After that it gradually shifts from ‘see’ and more becomes ‘feel’, but in the end it is still a perceptible difference. Generally one needs to double the framerate to get the same ‘feeling’ of difference. That’s to say, 30 to 60 feels about as big a difference as 60 to 120 rather than 60 to 90. Of course there is also a limiting factor of how quickly the rods and cones in the eye can physically react and then send this data to the brain. After ~100-140 the SnR drops off rapidly. Can some people still ‘feel the difference’ between 120 and 240 ever? Likely, but as camera can still take a picture of a very low light scene with no flash and still get some amount of data, its just not going to be very detailed.

For a game like Minecraft where there is no motion blur, it is very easy to tell the difference. However if motion blur (and other things) were applied, 30fps with motion blur can look very similar to 60 without motion blur. Games like Crysis had this back in the day because they know most people were going to get shit performance in the game, and they wanted people to put it at as high settings as possible, and motion blur is a great way to artificially boost perceived gameplay smoothness. You will find many console games these days applying smart amounts of motion blur in this way to keep gameplay perception smoothed out due to consoles having limited power, and the higher fps the make a game, the lower the graphical quality, so most console games go for 30fps+motion blur rather than a straight up 60+ with no motion blur required us computer gamer overloads can attain.

You will find if you start to get into shaders, they come with (sometimes not working >=|) motion blur you can turn on and off in a config. You will need a relatively beefy GPU to render it at playable rates (460GTX or better class). Being that we are playing FTB, your CPU is going to already be pushed to its limits unless its highend. For shaders http://www.minecraftforum.net/topic/1649321-147-152-beta-chocapic13s-shaders/ both look and have better performance than Sonics shaders right now.

Settings:
Milkyway25fps:0:0px/s
Soccer Ball 60fps:None:500px/s
Soccer Ball 30fps:1.0(realistic):500px/s

The balls will move across the sky and look pretty damn close to how smooth they move. Now change the soccer ball with 1.0(Realistic) motion blur to 0, and watch how it loses some of its smoothness. Hopefully your computers can handle it For me 25fps is minimum playable, or I start to enjoy myself less. I have my MC set to 25 all the time while I make my forge/bukkit/shaders setup so I dont get spoiled with 60. Also it is a good idea to set it lower like that as consistency in framerate also contributed to perceived fluidity. A consistent input can be more preferable than constantly jumping from 30 to 45 for example. (Console games lock at certain framerates like this as well).

Well 60 fps with no motion blur feels better than 30 fps with it.
Also do you think i should get shaders? They don't impact cpu performance do they? just gpu? I have 2x gtx 580s so i should be fine.

i didn't even know voxel caused such a fps decrease until I saw this thread and installing rei's instead
my oh my being able to use optifine multi core chunk loading and not having voxel slow shit to a turtles pace it's nice
my i5 3570k is choking on FTB. it's not just voxels fault, minecraft is horribly optimized, too.
Xycraft causes graphical lag, as well. I wish there were a way to get rid of all the quartz crystals being rendered when not visible

It's not too painful a process, but you'll also lose any quartz crystals you have in chests. (I was under the impression that wouldn't happen until I opened my quartz chest and found it full of sand )

Thanks for the information. My computer is pretty high end, but even if something goes wrong, I can just uninstall the shaders. Even so, backups are your friend. Those websites are cool.

And I just realized my posts derped.

Onwards, for science!

Hoping that XY will change that quartz to a solid non-light emitting block in world gen, and have the crystal drop as a mined resource that can be placed.

for me with voxel just lags fps a lot, I removed liteloader and all that stuff and replaced it with rei's, is much more stable, has been around for ages, and is a minimap, not a mob radar that shows caves that looks like a CIA device.

I agree, but I was just making a point that the gap in precived difference is less. Its a good way to artificially add the illusion of smoothness. Movies do this a GREAT deal, (mostly due to how film/CMOS naturally handles light) and is why they can get away with 24fps.

In terms of GPUs you have enough to run the shaders well, but FTB is very very CPU intensive. If you can run the game in the most bust sport with no shaders at 60fps then with shaders should be fine. Your GPUs are probably at around 10-15% while the CPU is likely doing as much as one core can handle. Shaders will (mostly) just make the GPU usage shoot upto either where your CPU is being the bottleneck, or your vsync, depending on shader quality settings. Its a balance.

I recommend anyone try the shaders. They will have a impact in performance but they are way better than they were in 1.4.x

Does mincraft use sli at all or is it pointless having sli turned on?

Im not 100% sure on that one, however even one of those GPUs should give you pretty fair performance on far. My 460GTX does about 30fps at 1152i with the 'ultra' shaders. 26FPS with DoF turned on. 'High' gets me about 40 and 'Med' gets me about 50. Its mainly when I start adding machines and my CPU begins to get harassed does my FPS start to fall.

Shaders are client side right? So servers don't need them?
