Quick Answer
A modded Doom 2016 setup needs little: 16GB DDR5, an 8GB VRAM GPU, and any SSD. The id Tech 6 engine is exceptionally efficient, so even with HD textures and reshade, Doom 2016 holds 120fps-plus at 1440p on a build around R14,000-R17,000 at Evetech.
RAM, VRAM and Storage Explained for Modded Doom 2016
Doom 2016's id Tech 6 engine is a benchmark for optimisation. 16GB RAM is ample; the game never needs 32GB. VRAM of 8GB covers HD texture packs and reshade comfortably, with 12GB giving extra headroom at 4K. A 1TB NVMe helps load times but is not essential given the engine's efficiency. The takeaway is that Doom 2016 is light to mod and runs fast on mid-range hardware without special requirements. A 1TB NVMe SSD is the single most cost-effective addition here, cutting load stutter that even strong CPUs and GPUs cannot mask. Use a dedicated mod manager and sort the load order before each session, which prevents most crashes long before hardware becomes the limit.
A Sensible SA Modding Build
An RTX 5060 Ti or RX 9070 (around R10,000-R16,000) with a Ryzen 5 9600X and 16GB DDR5-6000 runs modded Doom 2016 above 120fps at 1440p Ultra. Raise the frame cap in settings for high-refresh play. Install on any SSD for quick loads. Spend saved budget on a 144Hz panel, since the game's fast movement and high frame rate reward a high-refresh display.
