This setting works well with SSDs but is not recommended on HDDs. The shader cache stores these compiled shaders so that subsequent runs of the same game do not need to perform the shader compilation”. Shader compiles are normally performed each time a game runs and are a common cause of game-play stuttering. *Shader cache/Shader cache size on newer drivers – keep it on or on driver default value – “controls the maximum amount of disk space the driver may use for storing shader compiles. Since we are maximizing latency and FPS G-Sync is off and the maximum refresh rate is used. The setting will change if you use Adaptive sync. *Refresh rate – highest available to use the maximum potential of your monitor.

If you are on a laptop or on a PC that has thermal issues and are willing to sacrifice performance choose a different value that will help with power saving. *Power management mode is set to Prefer maximum performance to allow the GPU to boost to the highest clock and keep it that way for best latency and performance. If your games do not use more than 85% of your GPU leave Low Latency Mode off. Having this on Ultra might affect your FPS a bit since your CPU has to work harder. This represents mid-range up to high-end video card performance.* Low Latency Mode you can keep on On or Ultra as it helps with limiting queued frames, therefore, lowering input lag in games that do not use Nvidia Reflex technology. We are using an NVIDIA GeForce RTX 2080 SUPER FE and an NVIDIA GeForce RTX 2060 SUPER FE. We chose two video cards to use to collect all this data. We have two games benchmarked with a manual run-through, and two games benchmarks using the game’s built-in in-game benchmark runs. Game Performance – Finally, we will see if it all adds up to changing game performance between each power mode. Will it give us more or less GPU frequency? Will the card run faster under “Prefer Maximum Performance”? That’s the question. The goal here is to see if any of these power modes actually changes the potential of the GPU. GPU Clock Frequency – This one is very important we are tracking the GPU clock frequency in real-time as we play a game. GPU Temperature – We are also collecting GPU temperature data to see if any option is more demanding on the GPU or not. With these two different power data points we’ll have a good grasp on the power demands with each option. In addition to total system Wattage, we will report the Power Consumption that GPUz finds for the graphics card. Therefore, we will look at the total system Wattage at Idle and Full-Load in a game and compare them. Idle and Full-Load Wattage – Naturally, we need to find out which options affect power usage and by how much.

To test this practically, in a real-world environment we are taking several data samples that will be important to look at.
