Have been having terrible stuttering in this game due to 100% SSD usage. After a lot of troubleshooting, I noticed lowering texture quality to low fixed the stuttering. Wondering why I checked the VRAM usage in GPU-Z with it set to very high and sure enough... GPU-Z is reporting almost 8GB of VRAM being used at 1080p...

Makes sense because the VRAM is full so the game has to constantly swap textures from my SSD which is causing the 100% usage. Hopefully this is just a bug with AMD drivers since they haven't been updated for this game yet... but seriously, this is ridiculous...

What you see in GPU-Z (and in most monitoring programs) is the allocated VRAM, a lot of games allocate all the memory so they can use when they need it (wether it uses it or not), Assassins creed Unity and Syndicate do exactly the same.

I know nothing about the VRAM requirements of Rise of the Tomb Raider, but it seems strange that it would monopolize 8 GB. I would first use DDU to cleanly remove the drivers, and then reinstall, just to be sure that they aren't being glitchy. Also, would you mind listing your full specs, including your power supply mfg and model #?

Addendum: Also, when you state "100% SSD usage", what does that mean? And how did you conclude that? I'm not disputing your conclusion, I'm just trying to get a better understanding of your problem.

I uninstalled/installed the drivers when I updated to the newest AMD drivers a while ago. My PSU is a XFX TS 650w.

100% SSD usage meaning in task manager, it reports ROTTR.exe using 100% of the disk at ~220mb/s. The SSD/HDD LED on my case is also solid red the whole time playing the game.

Also in reply to the person talking about allocated RAM, it is also using a substantial amount of dynamic RAM (~514mb) which from my understanding is system RAM that can be used by the GPU if it ever needs to. So in total, the game is using 8.5GB of RAM. Btw, on low textures it uses just under 4GB which is still a lot for a game at 1080p.

I told you that because you are not the only one, and it could be normal for this game to use available VRAM. Beside lowering your settings I don't know what else can you do. Also he mentioned VSync (something about Vsync x2, and x3), but he has more powerful GPU so he turned it of I think, and on 980 ti game runs better than on 390/970. Maxed out settings in this game on 1080 with 390/970 are not possible if you want 60 fps... I don't have any other information that could help you.

AMD just released new beta drivers that patch support for this game and wow... Still 8GB of VRAM being hogged, but there is absolutely no lag, stuttering, or excessive disk usage anymore. Granted AMD should've had the drivers ready before the game was released to the public... but better late than never.
