BotW: high GPU load in buy/sell menus

[jn64]

Cemu version: f0938e1, ..., 6f985c3 OS: Fedora 36 GPU: NVIDIA GeForce GTX 1050 Ti Driver version: 515.76, 520.56.06 Game: Breath of the Wild (EU, v208 / 1.5.0)

Description

In BotW, there is abnormally high GPU load (+100% or more over average) in buy/sell menus.

• Only affects the standard NPC buy/sell menus. Doesn't affect any similar menu I tested: inventory, dyeing shop, Great Fairy, Hateno statue
• No input lag or frame drops (I've seen other issues about those in various menus, so this doesn't seem to be the same)
• FPS++ graphics pack:
  • With FPS++ (30FPS limit), the only effect is the increased GPU load.
  • Without FPS++, there is increased GPU load, and FPS drops from 30 to 20 in buy/sell menus (don't know if this is normal for the game).
• At higher internal res, the effect is more noticeable
  • 1280×720: 35% normal load to 75% in buy/sell menus
  • 1600×900: 40% normal load to 95% in buy/sell menus
• It's especially noticeable after ada8bbb which brought down the average load (:+1:)
• Possibly related issue on Windows (not mine): https://www.reddit.com/r/cemu/comments/xl3goc/shops_and_other_npc_interactions_drop_framerate/

Screenshots

I'm using gamescope to upscale so the reported resolution doesn't match the image size. Has no effect on the issue.

(1) Normal GPU load (~35%):

(2) High load in shop menus (~75%):

(3) For comparison, lower load in inventory (~15%):

Higher effect at 1600×900

(4) Normal load (~40%):

(5) Shop menus (~95%):

It increases GPU usage by 10% on Windows 10 with my RX 6950 XT, so I cannot imagine what kind of performance hit you getting with a low end GPU.

For me it doesn't affect whasoever, since GPU usage is always below 60%, but there is a clear jump in resource usage on the store page.

Same here, Fedora 36 and GTX 1050 ti. But in my case the FPS drops from ~30 to ~14fps.

Same experience Windows 10 19044 Cemu 2.08 and 2.07 GPU: GTX 1650 4GB GPU Driver: 522.25(Latest as of this post)

Going back to Cemu 1.26.2f solved the issue.

Same issue here, Windows 10, GTX 1070 with drivers 522.25.

I was able to reproduce the issue. GPU frequency scaling was intentionally disabled for this test

I don't know if this is out of the ordinary though.

I found that in all similar cases, the background is still active. Maybe this issue is caused by the low efficiency of blurring the background frame.

It could be something like that. This might be something that some tinkering with graphics packs can fix.

same experience too and if i use the same graphic pack in cemu 1.26.2，no framrate dropping appears，everything will work fine

Chiming in with the same issue, I get around 20fps with an open vendor screen with the blur effect, much higher FPS otherwise. This is with an M1 Max mac and the newest 2.0-x builds.

Also have this problem.

• Win 11 22H2
• GTX1080, Driver 527.37

Drops from 100-110 down to 50-55 after opening a shop.

[georgerusu017]

I can confirm that on M1 Pro it's the same problem. Fps drops to less than 15.

[Nerowaiss]

The problem still persists in more recent versions so I tried it in version 1.27.1 and everything works fine, something changed from this version to 2.0, I recommend using 1.27.1 that way you don't have to install the updates and dlcs

Cemu 2.0-28 Same issue

[Lucas-Morais-Freire]

Cemu 2.0-29 and its still happening
