Again, there’s no perfect solution to this one. CS:2 spent a good while in its beta while the team at Valve worked to update the game and improve its performance on a variety of PCs. Any modern gaming PC on the market should have no issue running the game, but if you’re still concerned, we’d recommend you check out the minimum system requirements found on CS2’s Steam page.
OS: Windows 10
Processor: 4 hardware CPU threads – Intel Core i5 750 or higher
Memory: 8 GB RAM
Graphics: Video card must be 1 GB or more and should be a DirectX 11-compatible with support for Shader Model 5.0
DirectX: Version 11
Storage: 85 GB available space
These aren’t particularly taxing, so anything modern should see you getting good FPS in CS2.
