-Snapdragon™ Game Studios developed Snapdragon™ Game Super Resolution (Snapdragon™ GSR or SGSR), which integrates upscaling and sharpening in one single GPU shader pass. The algorithm uses a 12-tap Lanczos-like scaling filter and adaptive sharpening filter, which presents smooth images and sharp edges.
+Snapdragon™ Game Studios developed Snapdragon™ Game Super Resolution 1 (Snapdragon™ GSR 1 or SGSR1), which integrates upscaling and sharpening in one single GPU shader pass. The algorithm uses a 12-tap Lanczos-like scaling filter and adaptive sharpening filter, which presents smooth images and sharp edges.
 
 Our solution provides an efficient solution for games to draw 2D UI at device resolution for better visual quality, while rendering the 3D scene at a lower resolution for performance and power savings.

 The technique has visual quality on par with other spatial upscaling techniques while being highly optimized for Adreno™ GPU hardware.

+
+Snapdragon™ Game Super Resolution 2 (Snapdragon™ GSR 2 or just SGSR 2) was developed by Qualcomm Snapdragon™ Game Studios; it's our temporal upscaling solution optimized for Adreno GPUs.
+
+Snapdragon™ GSR 2 strikes a better balance between performance and visual quality on mobile devices than other temporal upscaling methods. Its main goal is to improve the quality of the final image by reducing aliasing, flicker, and ghosting while increasing image resolution.
+
+By comparison, TAAU is a simple and fast upscaling version of TAA. It tends to do a good job of reducing aliasing in moving images but also amplifies TAA's shortcomings, such as ghosting. Other alternatives have been developed to produce better perceptual visual quality than TAAU, but these are notoriously slow on mobile GPUs, often introducing compute shader bottlenecks and consuming a lot of power.
+
+Snapdragon™ GSR 2 is an improvement on all fronts, ensuring applications retain their visual fidelity while being easy on power consumption.
