One of the dilemmas of gaming laptops equipped with a dedicated graphics card is juggling between the graphics part of the processor (iGPU) and the dedicated graphics card (dGPU).
Performance or autonomy, you have to choose!
Manufacturers can choose whether the iGPU manages the screen display or the graphics card. In the first case, the autonomy of the PC will be significant, but the performance in the game will be slightly reduced, since the iGPU must process the images before sending them to the screen, which increases latency and the frame rate (number of images per second) reduced. . In the second case, the graphics card manages the display, the performance is there, but the autonomy decreases drastically even when no game is started.
This is how Optimus technology works.

Nvidia and AMD have found the solution with Optimus Advanced and Smart Graphics Access Graphics respectively. These technologies are made possible by a so-called MUX chip, which allows you to switch between the rendering mode of the iGPU and the dGPU on the fly, thus providing autonomy and performance, the best of both worlds. However, this solution comes at a price (some so-called entry-level laptop PCs do not benefit from it) and we can observe a delay of 1 to 2 s when switching modes, especially on PCs with Optimus Advanced.
CASO to the rescue
Microsoft has therefore worked to offer instructions that make it possible to do without a MUX chip. With the Cross Adapter Scan-Out (CASO) function, the processing of images sent by the graphics card by the iGPU is less resource intensive.
The Windows Editor therefore reports a 16% increase in frame rate, a 27% reduction in display latency and a 45% reduction in error rates (crashes). For comparison, Nvidia claims an 18% increase in frame rate (+15% for AMD).
This is how AMD Smart Access Graphic works.

CASO is directly integrated into Windows 11 since version 22621.1413 (WINVER command for verification); The user doesn’t have to do anything except update their processor and graphics card drivers. However, you will need an AMD Ryzen 6000 processor, an Intel processor with an Iris Xe iGPU and Nvidia drivers higher than version 515 (we are at version 537.42).
The introduction of CASO is therefore good news for laptop PC owners who do not benefit from the Optimus Advanced or Smart Access Graphic options and no longer have to choose between performance and autonomy.
