About

Stop guessing whether a Steam game will run on your PC. Enter your hardware once — PC Game Checker instantly analyzes every Steam game page and gives you a personalized performance verdict.
🖥️ ENTER YOUR FULL PC SPECS
GPU, CPU, RAM, operating system, storage type (NVMe SSD, SATA SSD, or HDD), target resolution, and FPS goal. Set it once, works everywhere.
⚡ PERSONALIZED FPS ESTIMATES
Compares the game's requirements against your actual GPU and CPU. Shows a real FPS range calculated for your specific setup — not generic guesses.
🎛️ RECOMMENDED SETTINGS
Tells you whether to expect Ultra, High, Medium-High, Medium, or Low-Medium settings based on how your hardware stacks up.
🚫 HARD BLOCKERS — BEFORE YOU BUY
Flags real problems that will prevent the game from running properly:

GPU below minimum requirements
Not enough RAM
Game requires SSD but you have an HDD
Game requires Windows 11 but you have Windows 10
No Windows version available

⚠️ SMART WARNINGS

CPU bottleneck detected
SSD recommended but you have HDD
Partial or no controller support
OS compatibility concerns

🔍 UPSCALING SUPPORT
