Vega graphic cards users will reportedly enjoy better performance in World War Z with the new AMD driver.\r\n\r\nAMD released the 2019 Radeon Software Adrenaline 19.4.2 version, which will reportedly result in massive gains in performance. For now, however, only Vega graphics cards are included in the release notes.\r\n\r\nFor instance, AMD has noted a 24% boost in performance in the game from tests for Radeon VII graphics card. Meanwhile, for Radeon RX Vega 64 users, the boost is around 19%. This is supposedly one of the biggest bumps in performance after a driver package is released.\r\n\r\nThere are some known issues with this version. Among these include:\r\n\r\n- Flickering of the screen in multi-display setups\r\n- Fluctuations on the metrics overlay, as well as the Radeon Wattman metrics\r\n- Video playback issues on the Netflix Windows Store\r\n\r\nPreviously, the release of the 2019 Radeon Software Adrenaline 18.12.2 also registered performance gains. Some of the games included in tests are:\r\n\r\n- Assassin\u2019s Creed: Odyssey -- A 4% performance gain on Radeon RX Vega 64 card\r\n- DOOM -- A 5% performance gain on Radeon RX Vega 64 card\r\n- Shadow of the Tomb Raider -- A 3% performance gain using Radeon RX Vega 54 card\r\n- Strange Brigade -- A 7% performance gain using RX Vega 64 card\r\n- Wolfenstein II: The New Colossus -- A 5% performance gain using the Radeon RX Vega card\r\n\r\nHowever, in its release notes, AMD said that it noticed some issues on the 2019 Radeon Software Adrenaline 18.12.2. Among these issues include:\r\n\r\n- Lag in the mouse when running multiple displays. But only if one of the monitors is not in use\r\n- Not compatible with the Microsoft PIX\r\n- Radeon Settings will remain even if you uninstall the Radeon Software\r\n- Games may not be detected by the Upgrade Advisor, which will then recommend a workaround\r\n- Issues on auto tuning after activating the Auto Overclock GPU\r\n- Error message \u201cPort 58888 already in use\u201d may appear if you disable the AMD Link Server. However, this only happens if it\u2019s connected to the IOS device client\r\n- You may encounter problems with scrolling in the Scene Editor if you add many elements\r\n- Issues on the Radeon Overlay video player\r\n- Issues on control options on auto tuning\r\n\r\nThe Radeon RX Vega 56 wasn\u2019t mentioned, but it\u2019s safe to assume it will enjoy a performance gain, as well. After all, it\u2019s still built using Vega infrastructure.
