Limit on GPU presentations?
It seems your GPU's power limit is capped at 100W, which restricts performance in games. You might need to adjust settings or check for driver updates. Your CPU is limited to 60W, which is normal. Make sure both components are compatible and functioning well.
The CPU limitation comes from the R5 1600AF not handling more than 60W at its default setting. The GPU behaves differently. Initially, I’d run DDU in safe mode and reinstall AMD drivers to clear any custom power tables that might be causing the problem. If this doesn’t improve performance and you’re confident it’s a CPU issue, you can build a custom power table with power limits turned off. You can set this up manually or use MorePowerTool for automation.
I moved the power limit bar to the right on Catalyst and confirmed the limit is now 110W. (I tweaked it by 10). The CPU ran at 99.6% EDC. I looked up fixes and found that setting the maximum CPU state to 99% instead of 100% in Windows control panel power settings might help, though it still seems high. It’s probably a CPU bottleneck since it’s just a stock 1600AF, but my FPS feels lower than expected.
Power consumption doesn't always reflect speed. Focus on what your system actually needs rather than chasing higher watts. More powerful parts don’t automatically mean better results; sometimes they can hurt performance. Extra energy creates more heat, and if it overheats, performance drops sharply. Modern CPUs and GPUs handle power efficiently, making overclocking less useful lately. Often, the smartest choice is to lower voltage or frequency, improving efficiency so you get more performance per watt while keeping power use stable.
Chris Pratt’s comments highlight a distinct scenario. AMD claims the RX6600 draws 132W, but in practice, only 100W was available from the start, especially at higher resolutions like 2560x1600. Raising the power cap to its maximum briefly increased performance to 120W. Comparing this to Nvidia’s behavior, where a card rated for 150W would consistently hit that mark under full load, the RX6600’s performance seems inconsistent—especially noticeable in these tests.
