Texture pop-in in open-world games is one of those frustrations that feels like it should be solvable by pure willpower — but in reality it's a mix of GPU memory, streaming systems in the game engine, and crucially, how fast your storage can feed texture data. I spent weeks testing NVMe Gen4 drives while hopping between Cyberpunk 2077, Red Dead Redemption 2, Microsoft Flight Simulator, and a handful of open-world PC builds to figure out which specific Gen4 models actually make a noticeable difference, and how to set them up so that you see fewer "pops" and smoother streaming.
Why some NVMe drives reduce texture pop-in and others don't
Not all NVMe Gen4 SSDs are created equal. A drive can be listed as "PCIe 4.0" but the experience depends on a few critical factors:
In short: high peak numbers mean little if the drive drops off during a sustained streaming session. I prioritized drives with solid sustained throughput, high random IOPS, and real-world thermal behavior.
Models that actually reduce texture pop-in — my picks
These are the Gen4 drives I tested and saw a consistent reduction in pop-in. I list the practical reasons why each one helps.
| Model | Sequential Read (Max) | Why it helps |
|---|---|---|
| Sabrent Rocket 4 Plus | ~7,000 MB/s | Very high sustained reads and solid random IOPS; performs well under sustained texture streaming. Pair with a heatsink. |
| Samsung 990 Pro | ~7,450 MB/s | Excellent controller/firmware optimization and consistent performance; Samsung firmware updates and driver support are a plus. |
| WD Black SN850(X) | ~7,000–7,300 MB/s | Designed with gaming in mind. Good sustained behavior and low-latency random reads; WD also offers heatsink SKUs. |
| Seagate FireCuda 530 | ~7,300 MB/s | Top-tier endurance and excellent sustained performance—one of the best for continuous texture streaming on Gen4. |
| Kingston Fury Renegade | ~7,300 MB/s | High sustained throughput and competitive pricing; performs well in long sessions without throttle. |
All of these drives handled continuous streaming workloads better than entry-level Gen4 drives in my tests. The difference becomes obvious in dense urban areas or when flying over detailed terrain in simulators: textures load more consistently, and you're less likely to see a flat-gray patch briefly replace detailed textures.
How I test — what I watched for
I used repeated in-game run-throughs of the same scene, recording frame times and watching texture LOD transitions. The things I logged:
I also made sure GPU VRAM wasn't the bottleneck: if your GPU runs out of VRAM, textures will still drop in no matter how fast your drive is. So always pair a fast Gen4 drive with enough VRAM for the game's texture settings.
How to set up your Gen4 NVMe for best results
Buying a top-tier drive is only half the battle. Here's how I set up systems to actually reduce pop-in.
Practical notes — what to expect and what to stop blaming
Even with the best Gen4 drive, some pop-in is engine-related. Games with inefficient streaming or those that simply rebuild LODs on the fly will still show artifacts unless the developer patches the streaming system. Also, low VRAM causes texture eviction that no SSD can fix.
That said, in my experience a well-configured Gen4 drive like the FireCuda 530 or Samsung 990 Pro, installed in the correct M.2 slot, kept cool, and paired with the right BIOS and OS settings, produces a measurable and visible reduction in texture pop-in. If you want the most bang-for-buck: prioritize a drive with excellent sustained sequential read and strong random IOPS, add a heatsink, and make sure the game is installed there. The visual payoff is immediate in dense zones and flight sims — clearer, faster-loading textures and fewer surprise gray patches as you explore.
