Getting Started with the Modpack
All The Mods 8 is a large-scale Minecraft modpack that bundles together somewhere around 450 mods. It sits between the earlier ATM versions and the newer ATm9 in terms of complexity, but it still requires a serious amount of system resources and some patience to run without constant stuttering. The core concept is straightforward — you take a bunch of technology, magic, and exploration mods and force them to coexist in a single save file. That coexistence is where things get messy. To actually play this, you need to grab the CurseForge launcher. Download it from curseforge.com/download if you haven't already. Create an account, sign in, search for "All The Mods 8" in the search bar, and click install. The pack itself is roughly 3 to 4 gigabytes uncompressed, and with Java and its libraries it will take up about 5 to 6 gigabytes on your drive once it finishes downloading. Allocate at least 6 gigabytes of RAM to it in the CurseForge profile settings. Anything less and you will hit garbage collection pauses that make the game feel broken even on decent hardware. The first launch takes longer than usual because the pack is verifying mod signatures and generating optimized Java arguments. This can take between 5 and 15 minutes depending on your internet speed and whether your PC has to download optimized native libraries. Do not close the launcher during this process. I watched a video once where someone kept force-closing the window thinking it was frozen. It came back as a corrupted install and they had to delete the entire instance and start over.
Once it finally boots into the main menu, you need to create or load a world. If you are starting fresh, pick Creative initially just to orient yourself. The modpack comes with its own progression system through craft tweaker scripts and quest files, but you can mostly ignore those in the early hours unless you want a structured path. For most people, the first meaningful goal is figuring out which tech mod you want to invest in first. That decision shapes your entire playthrough.
The Tech Path and Early Game
The recommended starting point for most players is Immersive Engineering. It gives you basic power generation through manual and water-based generators, simple machine frameworks, and a logical progression path into more complex automation. The alternative of going straight into Create is tempting because Create has better visuals and a more intuitive workflow, but it is also significantly heavier on CPU performance. On a mid-range PC running at 16 gigabytes of RAM allocated, Create can drop your framerate by 15 to 20 percent compared to Immersive Engineering in the same scenario. Here is something most guides don't tell you: the order in which you unlock machines matters more than you might expect. If you pull power from a steam generator too early, the heat transfer between machines gets complicated because you need pipes, boilers, and water sourcing all set up simultaneously. Steam generators also produce significant pollution if you are running coal, which can trigger side quests or complications depending on your mod selections. A clean path is to start with a hand crank for initial power, then build a water wheel or windmill before touching steam. This gives you roughly 20 to 30 minutes of early-game stability before you graduate to combustion engines or turbines. The other thing nobody warns about is ore doubling. Nearly every tech mod in this pack has a crushing or hashing mechanic that turns one ore into two or three. The problem is timing. If you build a fully automated ore processor before you have built a basic smelter or furnace array, you will end up with an overwhelming surplus of dust and ingots that you have nowhere to use. The processing chains branch into at least a dozen different downstream recipes. One practical workaround is to build your crushing setup after you have already established a working electric furnace or a chain from at least one other mod. That way your output has somewhere to go immediately.

Common Problems and Workarounds
One specific issue that costs people hours is the JEI conflict with recipe rendering. Just After the first world loads, if you open JEI and scroll rapidly through certain mod categories, the game will freeze for 30 to 60 seconds or crash entirely. I hit this exact problem within the first week. The root cause is that JEI tries to render every possible recipe from every mod simultaneously, and some of those recipe definitions are poorly optimized. The fix is to install the Just Enough Items resource pack optimization patch and set JEI to only show recipes for the mod category you are currently browsing. You can do this by going into JEI settings, enabling "Only Show Owned Items," and turning on the render optimization toggle. This cuts JEI load times from roughly 12 seconds down to about 2 seconds when switching categories. Another edge case involves the world generation. ATM8 uses a modified Biomes O Plenty configuration that can generate extremely dense forests with massive trees in the overworld. These trees are fine visually, but the leaf decay mechanics are not properly configured in some server environments. If you clear a large area of forest near your base, the leaf decay can trigger massive chain events that lag the chunk loading system for several minutes. I encountered this when trying to expand my starting base into an adjacent biome. The workaround is to use a controlled burning strategy instead of manual leaf clearing. Place a few campfires in a line and use a torch to light them. The fire consumes leaves gradually without triggering the full decay cascade, and it takes about 10 to 15 minutes per acre instead of causing a server hiccup.
Progression Beyond the Early Game
After you have established power and basic automation, the next major milestone is usually Mekanism. It is a heavy mod but it provides solid tiered progression from basic metal processing all the way into multiblock structures and energy-intensive operations. The key insight here is that Mekanism's energy system uses its own internal units called Joules, and the conversion rates are not linear across tiers. A basic machine like the Digital Miner pulls around 512 Joules per tick at maximum output, but a thermal evaporation plant can draw up to 4096 Joules per tick. If your power grid isn't built to handle sudden spikes from multiple high-tier machines running simultaneously, the voltage will sag and everything slows down. The solution is to use Mekanism's energy cubes as buffers between your generation and your consumption. Stack at least three energy cubes between your turbine output and your machine input line. This gives you enough buffer capacity to absorb transient spikes without dropping below the minimum voltage threshold that triggers machine slowdowns. The magic mods in this pack are mostly Thyros, Ars Nouveau, and Botania. Each one has a completely different design philosophy and resource chain. Thyros is the most straightforward for beginners because it has a clear spellcasting progression tree with prebuilt spells. Ars Nouveau is deeper but requires you to understand glyph composition, which takes time to internalize. Botania is purely organic and rune-based, which means it integrates well with other mods but poorly with automated systems. I recommend spending your first 10 to 12 hours in-game exploring just one magic mod before considering a second. Juggling multiple magic systems simultaneously creates conflicting resource demands and makes it hard to identify which mod is causing a particular bottleneck.
Performance and Server Notes
If you are running a dedicated server, expect higher latency than singleplayer. The mod count alone adds approximately 2 to 4 seconds of chunk loading time on a machine with an SSD and 32 gigabytes of RAM. On HDD storage, chunk load times can stretch to 8 to 12 seconds in heavily generated areas. The server also requires a minimum of 12 gigabytes of RAM allocated to the Java process, and ideally you should enable the G1GC garbage collector flags. Without those flags, the server will experience periodic freezes lasting 3 to 8 seconds every 15 to 20 minutes during normal gameplay. This is not a mod issue. It is a JVM tuning issue that affects every large modpack running on default Java settings. There are some mods in this pack that are simply not worth the performance cost. Sky Achievements, for example, adds visible achievement popups that each consume memory and processing. Performance impact is negligible on a loaded PC but noticeable on anything under 16 gigabytes of allocated RAM. Another one is the extended terrain generation depth, which goes beyond Y-64 into bedrock-level mining. The extra vertical generation adds about 8 to 12 percent more world generation time but provides very little practical benefit since most mods cap their ore generation well above that depth. If you want to tweak this, look for the worldgen config file in the config folder and adjust the max generation height accordingly.
What This Pack Still Struggles With
Despite improvements over earlier versions, ATM8 still has persistent issues with mod conflicts around crafting table interactions. When you place a crafting table from one mod and a crafting table from another mod next to each other in the same room, there is a small chance that the UI will render incorrectly. The recipes display but clicking them does nothing. I have seen this happen with Applied Energistics crafting terminals alongside regular crafting tables. The workaround is to separate them by at least three blocks of distance or to use only one type of interface mod at a time. It is a minor annoyance but it catches people off guard because there is no warning indicator in the UI. Also worth noting: the quest book in this pack is functional but incomplete. Certain endgame content, particularly related to the Nether and End dimensions, has no associated quests. This is not a bug. It is a design gap in the quest authoring process. If you rely on quests for progression guidance, you will hit dead ends around hour 30 to 40. The alternative is to keep a browser open with community wiki pages or to browse the mod documentation directly. Neither is ideal but they work better than following an incomplete quest chain into a wall.
