Total War: ROME II - Emperor Edition PC Hardware Guide
Official requirements explained
The official minimum asks for a 2 GHz dual-core Intel processor (or a 2.6 GHz single-core). On our tier scale that sits at the level of an AMD Athlon 64 X2 6000+, a very old entry-level CPU. The minimum GPU is a 512 MB card with DirectX 9.0c support (shader model 3), which corresponds to integrated graphics like Intel HD Graphics 4000. The minimum asks for 2 GB of RAM and 35 GB of storage, and does not require an SSD.
The recommended level moves up to a 2nd generation Intel Core i5 or newer, which we place around the Intel Core i5-4460, still an early mainstream chip. The recommended GPU is a 1024 MB DirectX 11 compatible card, which our scale also places at the Intel HD Graphics 4000 level, so the publisher did not draw a big distinction on the graphics side. Recommended RAM is 4 GB, storage stays at 35 GB, and an SSD is again not required.
In practice the gap between minimum and recommended shows up mostly in CPU generation and memory. A machine that only meets the minimum will run the game but may struggle in large campaigns and big battles. Meeting the recommended level gives noticeably steadier play. The publisher did not list anything above the recommended level, so how much headroom you want beyond that is your call.
The requirements list does not specify anything beyond these two levels.
Recommended builds for three budgets
The entry build pairs cards such as the AMD Radeon RX 6500 XT, Intel Arc A380 or NVIDIA GeForce GTX 1650 4GB with a CPU like the Ryzen 3 3100 or Core i3-10100F, and 16 GB of RAM. It suits players on a tight budget who play at 1080p and accept medium settings, and it sits well above the official minimum.
The mainstream build offers the GTX 1660 or RTX 3050, paired with a Ryzen 5 3600 or Core i5-10400, again with 16 GB of RAM. It suits players who want steadier performance and higher settings, and it gives more room in large campaigns than the entry build.
The high build uses cards like the RTX 2070 Super, RX 6650 XT or Arc B570, with a Ryzen 5 5600 or Core i5-12400 and 16 GB of RAM. It suits players who want to play at higher resolutions or settings, or who run other software alongside the game. Since the game itself is not very demanding, this tier is about headroom rather than necessity.
Graphics settings with the biggest impact
In large strategy games the settings that usually cost the most are shadow quality, volumetric effects, simulation and crowd density, and view distance. When many units are on screen, unit count and battle simulation often weigh more heavily than resolution alone, so those are the first things to adjust. Shadows and volumetric lighting often cost more than they add visually, which makes them good candidates to lower first.
Texture quality and basic anti-aliasing are worth keeping if you can, since they improve clarity for relatively little extra cost. If your card has limited VRAM, reducing textures and shadows tends to help the most.
If your GPU supports DLSS, FSR or XeSS, upscaling generally lets you render at a lower internal resolution and scale up the output, which is a practical way to balance quality and smoothness. How well this works depends on whether the game supports it and on your GPU model; the requirements data does not cover this, so check the in-game options.
Laptops and handheld PCs
Laptop GPUs often share names with desktop cards, such as an RTX 3050 or GTX 1660, but their power limits and cooling are usually weaker, so real performance is noticeably lower than the desktop version. When choosing or configuring a laptop, look at the model suffix and the total graphics power (TGP), and watch for thermal throttling during long sessions. Using the power adapter and keeping vents clear helps sustain performance.
Handheld PCs such as the Steam Deck or ROG Ally are portable PCs with power-limited integrated GPUs and CPUs. In general they work best at lower resolutions and lower settings, and you can use the built-in performance tuning options. We have no Steam Deck verification data for this game, so we cannot give a compatibility rating; check real-world reports and try it yourself before relying on it.
Storage and memory
The official minimum asks for 2 GB of RAM and the recommended is 4 GB, but on today's systems 16 GB gives comfortable room for the game and background programs. Running two sticks in dual-channel mode usually helps overall performance more than one large stick, especially in CPU-heavy scenes or with integrated graphics.
The listed storage requirement is 35 GB. Leave extra space for updates and save files. An SSD is not required, but it noticeably shortens loading times and is worth it if your budget allows. A mechanical hard drive will still run the game, just with slower loads.
Updates and mods also take up space, so check that your drive has enough free room before installing to avoid failed updates.
