How to Boost FPS in Dota 2 Using AMD FSR
Should You Use AMD FSR in Dota 2?
AMD FSR’s impact on Dota 2 was quite minimal in our experience. We were not able to notice any significant FPS boosts on resolutions like 1080p and 1440p. The image quality gets compromised too much in most scenarios in exchange for the minimal increase of 10-30 frames per second, which makes it not worthwhile. Despite the image quality is less compromised when the FSR is reduced to around 50%, FPS still doesn’t significantly increase.
Therefore, we recommend not using AMD FSR for Dota 2. Just lowering your general Dota 2 performance settings would yield better performances outperforming FSR in Dota 2.
In 1080p and 1440p, this results in a lesser image quality sacrifice and a better performance boost. On the other hand, AMD FSR could potentially be useful if you are playing the game at 4K, and cannot get the maximum FPS that your monitor supports. Enabling AMD may lead to a noticeable increase in the number of FPS in some situations based on your 4k setup.
