Can you run Operation: Black Mesa?
Older hardware holds up here: Operation: Black Mesa runs on modest graphics, with NVIDIA GeForce GTX 960 or Greater enough to meet the minimum. Add 4 GB of RAM and a mid-range CPU and a PC several years old will play it fine.
Bottleneck: GPU
Projected by resolution
| Resolution | Projection | Headroom |
|---|---|---|
| 1080p | Comfortable | 1.7x |
| 1440p | Borderline | 0.96x |
| 4K | Below the bar | 0.43x |
A projection, not a measurement. We scale the published GPU requirement by pixel count, since 1440p draws 1.78 times the pixels of 1080p and 4K draws 4 times as many, then compare against RTX 3060 / Ryzen 5 build. The publisher did not state a target resolution, so 1080p is assumed as the baseline. We hold no frame rate data, so no FPS figure is claimed. Headroom above 1 means the reference machine has room to spare at that resolution.
