Try this.
1. Open Registry Editor
2. On top navigation ''Edit'' click ''Find'' Type ''Ulps'' wait for search to end.
3. double click ''EnableUlps'' change 1 from to 0, click ok and close registry editor. DO NOT CHANGE ANYTHING ELSE.
4. Other things you can do is such as clear shader cache in amd panel and then put windows power plan to high performance and then restart the pc.
When you run the game for first time it'll feel like stuttering but let shader sync and catch up. but after that stuttering never occur. But keep in mind. This ''EnableUlps'' keeps reverting to enabled every time you update amd radeon driver. so each time you need to manually disable from registry editor.
