![]() ![]() ![]() The thirst for retro gaming amongst gamers of a certain again hasn’t diminished in 2019, and so it’s no surprise that Integer Display Scaling is one of the features most requested by AMD GPU owners. It will be exciting to see if Radeon Boost can be adapted to other control mechanisms, particularly Virtual Reality HMDs, and whether the AMD-powered next-generation consoles leverage it. The claimed performance benefits are significant however, made even more impactful because gains are made during events which drop frames the most rather than topping-up already high frame rate periods. The technology is currently compatible with only a handful of titles, and with GPUs as recent as the RX 400 series (Polaris). Shader resource allocation isn’t changed across the frame by it (unlike, for instance, the VRS implementation utilised in Wolfenstein II: The New Colossus), and it doesn’t indicate compatibility with VRS in this AMD driver or hardware generation. It’s important to note that Radeon Boost isn’t what’s typically referred to as a ‘Variable Rate Shading’ technology. We infer from the materials presented that the texture quality algorithm is tied to mouse movement directly, possibly captured after it is parsed by the game engine, and are currently awaiting clarification and more detailed information on precisely how it works. Radeon Boost is directly tied to camera movement, and so doesn’t trigger in canned benchmarks such as 3DMark Firestrike or those shipped as an in-game tool. ![]() Furthermore, due to the relationship between frame rate and how we perceive detail, little to no perceptible difference in quality can be seen during this short period if utilising FreeSync. When the driver detects this movement it will drop the rendering resolution down a specified minimum (50-87%), helping to maintain high frame rates during crucial periods, before returning to normal. Radeon Boost is a novel approach at alleviating the frame rate drops caused during fast user-controlled camera movement in game. ![]()
