AstrixAU Posted December 29, 2019 Posted December 29, 2019 (edited) Hi guys, Please try this game with an AMD card running 19.12.3 I originally wrote this for AMD but also have to post it here. IL-2 stutters on AMD's latest driver 19.12.3 because of the Radeon overlay breaks IL-2 performance in fullscreen, no other game does the overlay restroy performance and create huge stuttering. The overlay always affected this game in the past if you brought it up, your FPS would drop to 10fps and the game would stutter. Now the FPS stays high "apparently" but it feels like 10 fps as it stutters like hell and is unplayable. For me the Radeon overlay only works if I toggle Adaptive sync on my LG 27GL850 monitor while gaming. The overlay then works fine in BF5 and PUBG but doing this on IL-2 makes it stutter as it has with IL-2 in the past if you brought up the overlay, I am sure I brought it up on here before or with AMD. I will be letting them know about this too but IL-2 has had a issue with the overlay way before this new bug that disables it. So the overlay bug on 19.12.3 is making the game playable for now as it only works if I toggle Adaptive Sync on my monitor while gaming. If the overlay worked out of the box the game would be stuttering as hell if there was no way to disable it as it comes on automatically when gaming to tell you what the key-bind is to bring the overlay up in game.. My system includes. Windows 10 64bit 1909 (latest update) i7 4770K RX Vega 64 LC - 19.12.3 - 2020 driver. Edited January 4, 2020 by =IL2AU=astrix_au
AstrixAU Posted January 4, 2020 Author Posted January 4, 2020 (edited) Have the devs here tested IL-2 with the latest driver 19.12.3 and see if the overlay also affects the performance for them. Not sure if you can disable the overlay in the Radeon settings but my Radeon Driver overlay in fullscreen only works after toggling adaptive sync on my LG 27GL850 monitor once per boot. Before doing this it locks up the mouse but nothing appears, once you press the hotkey to hide the overlay the mouse unlocks again. The overlay is very handy especially for the TAW multiplayer server as the overlay has a browser that you could use for https://il2missionplanner.com/ while playing the game without leaving fullscreen. Other games perform great with the overlay and it's only IL-2 that is affected. This AMD overlay bug in IL-2 that ruins the performance has been around for a very long time on IL-2 and AMD drivers going back a very long time.
