Unfortunately not really. But I found a way to make it somewhat playable. My 5700XT downclocked in Fortnite to about 800 mhz. Locking the clock to 1900mhz didnt work, the clock still spiked down which resulted in more stutters. The somewhat solution I found was disabling power saving things in the cards bios, which brings the risk of bricking the card. For me it worked tho. Now I can lock my clock to 1900 mhz in Fortnite and it stays there stable. I still get drops to 90 fps but its far rarer than before.
If you want to do it, youll find a tutorial here. If you have done it create a profile for fortnite in wattman where you lock the clock at almost max speed, as seen in the video. You may want to create a custom fan curve because the card gets a bit warmer because it stays at the clock youve put in as long as the game runs. If you want to do it do it at your own risk. Allthough the chance of bricking your card is very very low, if you mess something up it still can happen so be cautious!
