Hey all, I have noticed a weird issue raytracing on the PC. For reference, I have a 3070 and a Ryzen 9 3900xt. What I notice is that for some, but not all, raytracing games the games tend to display what feels like a memory leak. For those that don't know, a memory leak is basically when a game doesn't efficiently clear VRAM periodically leading to the memory becoming too saturated and the game's framerate may plummet from, say, 60 FPS to 30-20 FPS or lower until eventually the game crashes. This usually happens over time, as the memory needs to become saturated first, and is fixed by restarting the game.
I first noticed with Cyberpunk, then RE 8, and now Dying Light 2 that when RT is on the games will run at 60 FPS until about an hour or so of play and then drop frames until eventually it's running in the 30-40 FPS range. Restarting the games fix the problem. But both Metro Exodus and Control didn't have this problem. So I though maybe these three games were simply unoptimized for RT. I mean, Dying Light 2 is still being worked on seemingly. But I don't hear people having issues with this specific problem. That it's only when RT is on as well makes me think there something about how RT is being handled that causes these problems.
Have any of you had a similar problem with RT in games or heard of others having this issue? I'm curious what is actually happening and if there's anything in my control to fix it. I mean, at the end of the day, restarting a game periodically is a nuisance but not the end of the world. But I am curious and if there were a fix I could implement I'd like to try it.
