Building a Hardware Performance Calculator for the Rage 9 Engine (GTA 6)

Hey Dev.to community 👋

With all the hype around the leaked architectural changes for the upcoming Rage 9 engine (GTA 6), I noticed a gap: gamers have no reliable way to test if their current rigs will actually handle the load.

We already know the new engine will be rendering a massively dense open world. If you look at the sheer scale of the projected interactive Leonida Map and the heavy volume of tracked collectibles scattered across the state, the CPU draw calls and GPU VRAM load will be unprecedented.

To help gamers prepare for this specific rendering stress, I built a lightweight web tool that analyzes a user's specific CPU and GPU against the expected specifications.

You can test the live tool here: SpecVI GTA 6 FPS Calculator and GTA 6 System Requirement Tool

⚙️ The Logic: How the Calculator Works
The GTA 6 FPS Calculator estimates your PC's performance in Grand Theft Auto VI by simulating the RAGE 9 engine's expected workloads.

Input: You select your exact GPU, CPU, RAM, target resolution, and desired graphics features (like Ray Tracing or DLSS/FSR).

Analysis: The algorithm evaluates your hardware against specific bottlenecks. It penalizes setups with under 12GB of VRAM (which causes texture stuttering), flags CPU weaknesses in heavy physics or AI tasks, and adjusts scores based on a GPU's ray-tracing efficiency.

Output: The tool delivers an estimated Average FPS, assigns your build a performance tier (ranging from "God Tier" down to "Upgrade Needed"), and pinpoints exactly which component you should upgrade if your system is bottlenecked.

🛠️ What's Next?
I'm currently working on expanding the component database and refining the VRAM weighting to better simulate open-world rendering bottlenecks. If any devs have feedback on the matching algorithm, the UI, or suggestions for the tech stack, I would love to hear it!
