Total War: WARHAMMER III PC Hardware Guide
Official requirements explained
The official minimum CPU is listed as an Intel i3 or Ryzen 3 series processor. In our tier reference that sits around an Intel Core i3-3220, which is an entry-level chip. The recommended CPU is an Intel i5 or Ryzen 5 series, roughly comparable to an Intel Core i5-4460. The gap between the two is not large, but for this game core count matters more than raw single-core clock, because the large unit counts and AI decisions keep the processor busy.
On the graphics side, the minimum is an Nvidia GTX 900 or AMD RX 400 series card, or Intel Iris Xe integrated graphics, which puts it in the integrated or very early entry band. The recommended tier is a GTX 1660 Ti, RX 5600 XT or Arc A750, which is roughly the RTX 3050 class of 1080p mainstream cards. Meeting the recommended tier generally means comfortable play at 1080p on medium-to-high settings.
Memory is listed as 6 GB minimum and 8 GB recommended. Both figures are on the low side for modern use, so for real play I would plan on 16 GB to leave room for the operating system and background apps during long late-game campaigns. Both tiers list 120 GB of storage, and an SSD is not officially required.
The publisher does not list requirements above the recommended tier, so anything beyond that is a judgment call based on general experience, such as choosing a newer multi-core processor and a stronger mid-range or high-end graphics card.
Recommended builds for three budgets
The entry budget centres on cards like the GTX 1650 or GTX 1660, or the RX 6500 XT, paired with a newer Ryzen 3 or Core i3. This combination can reach the official recommended tier and suits players who want to finish the full campaign at 1080p on medium settings.
The mainstream budget is where the game fits best. A GTX 1660 Ti, RX 5600 XT or RTX 3060 8GB handles the graphics side, and a mid-range Ryzen 5 or Core i5 covers the processor. Because this is a CPU-heavy title, putting more of your budget into the processor often pays off more than adding GPU power alone.
The high budget suits players aiming for 1440p or higher quality. Options include the RX 6750 XT, RTX 4060 Ti or stronger cards, paired with a newer six-core or better processor such as a Ryzen 5 5600X, Core i5-12400 or Ryzen 7 8700G. Like the other two builds, 32 GB of memory keeps the system from becoming the bottleneck.
Graphics settings with the biggest impact
In large strategy games like this one, shadows, volumetric effects and particle detail tend to cost the most. Their visual payoff can be small compared with the load they add to the GPU. If you need to lower something, start with shadow quality and volumetrics, which usually free up the most headroom.
Because the bottleneck in this title is often the processor, the CPU-related options deserve attention too: unit draw distance, crowd density and physics simulation detail. In late campaigns with doubled unit counts, lowering these can smooth things out more than tweaking visual effects, and they mainly affect large battles rather than everyday play.
Upscaling technologies such as DLSS, FSR and XeSS render at a lower resolution and rebuild the image at a higher one, reducing GPU load without a large visual penalty in most cases. Availability depends on your graphics card, and results vary, so compare them yourself before deciding.
Laptops and handheld PCs
Laptop GPUs often share a name with desktop cards, such as an RTX 3060 Laptop versus a desktop RTX 3060, but real performance can differ noticeably. Laptop versions run under lower power limits and cooling is more constrained. When comparing against the official requirements, judge the specific machine's power and cooling design rather than the model name alone.
When gaming on a laptop, plug in the charger and select the high-performance power mode, otherwise the system may cap power. Sustained play can also trigger thermal throttling, so keeping vents clear and using a cooling pad helps maintain steady performance.
Handheld PCs such as the Steam Deck or ROG Ally are general-purpose devices, and game performance is bounded by their built-in processor and graphics hardware. We do not have verification data for this title on handhelds, so we cannot give a specific rating. In general, large strategy games need more settings adjustment on handhelds, so start with low settings and a reduced resolution and judge from there.
Storage and memory
The official minimum memory is 6 GB and the recommended is 8 GB. Since the operating system and other programs also use memory, 16 GB is the practical target for real play, and 32 GB gives extra headroom for large maps and crowded battles. Install memory in dual-channel pairs, such as two 8 GB sticks or two 16 GB sticks, which provides better bandwidth than a single large module.
The listed storage requirement is 120 GB. Beyond the game itself, leave spare room for updates and save files so you do not run short of space soon after installing. An SSD is not officially required, but if you can, install on an SSD, since faster reads cut load times noticeably, especially when the game reads large saves and map data often.
A traditional hard drive can still run the game with longer load times. If space is tight, consider installing the game on an SSD and moving less-used data to a hard drive.
