Arc’s first generation graphics cards, called Alchemist, have been on the market for about 10 months. During this time, Intel has done a lot of work in the field of drivers and significantly improved the performance in older games using, for example, DirectX 9. In the new video, the company also boasted that the performance in games with DX11 increased by an average of 19% from the original drivers. However, by far the most interesting part of the video is about a brand new metric that Intel calls “GPU Busy”.
When measuring performance, of course, we are used to looking at the number of frames per second (current / average), the lowest values (the so-called “1% lows”), as well as the frame time, that is, the time between individual frames. Such a graph usually shows the “fluency” you feel while playing. No matter how high the FPS is, if the frame time is unstable, the game feels choppy. However, just the time between shots doesn’t tell the whole story, because there’s a lot going on in the background.

This is where GPU Busy should help, which shows the time it takes for the graphics card to render an image. If we compare the data with the times between frames, we get a picture of where the “brake” is. The ideal situation is, of course, if both values are equal, but it can happen that frametimes are significantly higher than GPU Busy, which means that the processor is a bottleneck and the game does not use the full potential of the video card.
If you want to change the GPU load in the game, you can download the recently released PresentMon program, which was created by Intel to clearly overlay interesting information. In the settings, you can configure a lot of things, and most importantly, PresentMon works on all video cards, not just on Intel. At the same time, it is open source, so anyone can look at the source code and possibly change it.
Of course, this is not an omnipotent tool, even from a comparison of frametime and GPU load, it is impossible to determine exactly what the problem is, there can be many reasons. In any case, Intel’s Tom Petersen says they will continue to improve PresentMon and the plan is to show the user what’s hindering performance the most.
