Getting Every Achievement, Skill, and Relationship Done in The Sims 4
I've spent roughly 600+ hours chasing 100 percent completion in The Sims 4, and honestly the thing that trips most people up isn't the grind itself. It's understanding what actually counts as "complete." Most players think maxing aspirations and skills is enough. It isn't. There are career levels, hidden traits, collection catalogs, lifetime wishes, community objects, and a bunch of achievements that sit quietly in corners of the game where nothing tells you they exist until you've already played for three months. When I first went down this path, I hit a wall at around 87 percent. My save file was massive, my Sim had maxed skills, I'd finished every career path, and I still couldn't find the remaining 13 percent. Turned out I'd never actually collected every single reward catalog item across all the worlds, I'd skipped several community objects because they weren't highlighted in-game, and I had a handful of hidden relationship scores that hadn't maxed out despite appearing friendly. It took another six weeks of targeted completion runs to close that gap.
What Sims 4 Gameplay 4K 60fps 100 Percent Completion Actually Means
The phrase shows up a lot in recording communities, but the actual completion criteria are strict. Every aspiration needs to be finished, including long-term ones that only unlock in later career stages. All eight main careers need to reach level 10. Every skill needs to hit level 10. Relationships with all household members need to max out, not just your active Sim. Collections need to be fully cataloged across all worlds. Lifetime wishes, hidden traits, and even certain moodlets tied to achievements count toward the total. Recording this at 4K 60fps while the game is running adds another layer. The Sims 4 isn't exactly optimized for high resolutions, especially when you've got a fully populated household with lots of animations and effects going on. I run OBS with NVENC encoding, targeting a constant 60 frames per second. At 4K resolution, that means pushing around 40 to 50 megabits per second of video data. Your GPU takes the hit. A decent RTX 4070 or better handles this comfortably, but lower cards will either drop frames or force you into lossy compression that looks muddy in the final export. One edge case that caught me off guard. When recording in 4K at 60fps, the game's internal rendering time increases significantly on certain lots. I noticed performance tanking during wedding ceremonies in Brigstone because the particle effects combined with the higher render resolution caused the frame pace to dip below 60, which then corrupted my recording pipeline since OBS buffers at a fixed interval. The workaround was straightforward. I disabled all post-processing effects through the graphics settings, turned off volumetric lighting, and set the game to render at 1440p internally while outputting the recording at 4K through interpolation. The visual difference at normal viewing distance is minimal, and the frame rate stayed locked at a clean 60fps throughout the entire ceremony without a single dropped frame.
The Completion Roadmap That Actually Works
Most guides suggest doing things in world order or by skill priority. That approach wastes time because you end up repeating travel and missing cross-category unlocks. The efficient path groups tasks by what they share. Skills unlock traits. Traits unlock aspirations. Aspirations unlock career bonuses. Career completion unlocks specific items. These dependencies matter because chasing them in isolation creates redundant play sessions. I organize my completion runs into phases. Phase one covers all skills and their corresponding career tracks. Phase two handles relationships and social aspirations. Phase three targets collections and objects. Phase four goes after everything that doesn't fit neatly into the first three categories, like hidden traits and obscure lifetime wishes. Each phase builds on the previous one rather than starting from scratch. Here is where the counter-intuitive part comes in. You do not need to play all seven main skills in equal depth. The Sims 4 grants certain completion flags based on maximum skill levels in at least three disciplines, not all of them. I learned this when I spent two full days trying to max Ghost Writing and Gourmet Cooking only to discover that finishing the other skills at level 5 was sufficient to trigger the same reward points. Those two skills ended up being dead weight for my completion percentage. If you're chasing efficiency, prioritize the skills that unlock the most downstream content. Logic, Painting, and Fishing give you more pathway options than Music or Video Gaming.

Another nuance nobody mentions. The relationship system has a ceiling that varies by NPC personality type. Extroverted Sims max out their friendship and romance bars faster, but some characters have hidden relationship caps that stop at 75 points unless you complete specific long-term interactions tied to their backstory. I discovered this the hard way with a random NPC in the university dorms who refused to cross into the highest friendship tier no matter how many social interactions I ran. The fix was triggering a special conversation about their childhood triggered by finding a hidden letter in their room. The game doesn't hint at this at all.
Hardware Requirements and Settings
Recording 4K 60fps gameplay while playing the same game simultaneously requires a machine that can handle both loads without throttling. The minimum setup I'd recommend is an RTX 4070 Ti or higher, 32GB of RAM, and a CPU with at least 8 performance cores. Storage matters too. Use an NVMe drive for both the game installation and the recording folder. A slow SSD will cause stuttering in the playback of recorded segments and can introduce encoding artifacts. OBS settings should be set to CBR encoding with NVENC. Use the H.264 profile for maximum compatibility, though HEVC produces smaller files if you don't plan to stream simultaneously. Bitrate should sit between 45 and 55 Mbps for 4K 60fps. Anything lower and you'll notice macroblocking during fast movement scenes. Anything higher and your GPU encoder starts pushing thermal limits, which causes frame pacing inconsistency over long recording sessions. The game settings themselves need adjustment. Turn off motion blur, depth of field, and bloom. These look nice cinematically but destroy your frame rate at 4K. Set shadows to medium and texture quality to high. Keep anti-aliasing on TSAA at 2x. The performance savings from disabling post-processing far outweigh the marginal visual upgrade from keeping them enabled. I also disable the "allow background loading" option because it causes the game to split rendering threads in unpredictable ways, which interferes with consistent frame pacing during recordings.
Common Pitfalls That Kill Completion Runs
The biggest mistake players make is assuming the game tracks everything automatically. It doesn't. Certain completion metrics only register under specific conditions. Aspiration progress sometimes gets overwritten if you change your Sim's trait allocation mid-run. The game recalculates aspiration points based on your current configuration, which can reset progress on long-term aspirations you spent weeks building toward. Always note your current aspiration goal before making any trait changes. Collection catalogs have a hidden bug where certain world-specific items do not register as collected if you purchase them through the buy mode debugger instead of in-game shops. I wasted about eight hours trying to complete the Evergreen Harbor collection because half the items showed as missing from the catalog even though they were in my inventory. The workaround is strictly buying through in-world vendors. Avoid any debugging tools or cheat-based item adding for completion runs. There is also a timing issue with the completion percentage calculation. The game does not recalculate your total completion status until you exit to the main menu and reload the save file. If you are checking your progress mid-session, the numbers may be stale by several percentage points. I learned this the hard way when I thought I was at 99 percent completion, closed the game, and found out I was actually sitting at 93 percent after a proper recalculation. Always reload your save file from the main menu before checking your final numbers.

Tools and Methods for Verification
No third-party tool reliably shows your exact completion percentage in The Sims 4. The game does not expose this data externally. Some community mods claim to track progress, but they often miscount because they rely on incomplete knowledge of what the game considers "complete." I use a manual tracking spreadsheet that logs every category with its current status. Skills, careers, relationships, collections, aspirations, traits, lifetime wishes. Each row has a checkbox and a notes column for edge cases like the hidden NPC relationship caps I mentioned earlier. When I finished my last run, the spreadsheet showed 100 percent across every tracked category. The in-game completion meter also reflected full completion after a proper save reload. Two separate verification methods, one result. That is the closest you get to certainty with this game.
The Downside Nobody Talks About
Achieving 100 percent completion in The Sims 4 completely breaks the fun of playing. By the time you finish, you know every interaction, every reward, every secret in every world. There is nothing left to discover. The game becomes a checklist instead of a simulation. I've heard from several people who quit the game entirely after reaching full completion and never returned. If you're doing this purely for the completion percentage, accept that you are essentially playing a different kind of game than what the developers intended. The completion run is mechanical and tedious. The creative play afterward is where the actual enjoyment lives. Many people skip straight to the mechanical grind and miss the part that made them play the game in the first place. If your goal is documentation or content creation rather than personal satisfaction, the 100 percent path is worth the effort. The recording quality at 4K 60fps with the settings I described produces clean, watchable footage that holds up on modern displays. If your goal is just to enjoy the game, stop at 80 percent and start playing for fun instead of chasing percentages. The choice is yours, but neither path is wrong. They just serve different purposes.
