Bottleneck PROMEC SYSTEMS LLC

Bottleneck measures a Windows PC's processor, memory, storage and graphics, compares each with what parts of its class achieve, and reports how much of the machine's own potential it is delivering. It looks for the problems that cost the most and are invisible without opening the case or the firmware: memory running below its rated speed (XMP or EXPO off) or in single channel, a monitor running below its refresh rate or plugged into the motherboard instead of the graphics card, hardware-accelerated GPU scheduling switched off, restrictive power plans, overheating and failing drives. It can also measure a game while you play, using Intel PresentMon, and say whether the processor or the graphics card held it back. The free version scans, benchmarks and scores with no time limit. Paid licences are perpetual and checked offline, and nothing about the machine is uploaded unless you choose to share anonymous results.
