Game cranks up to 100% GPU usage on start o_O

[rebb]

Just starting the game up after playing it last time a few years ago, i noticed how laggy it is now, and according to Rainmeter, GPU usage is immediately cranked to 100%.

This is very scary tbh, and i guess that the game might be running at too high framerate or something similar.

Ok, maybe it's not VSync related. I just forced VSync via the NVidia panel globally, GPU use still cranks to 100% on start, and the game is slow.

I don't recall this being the case a few years ago, so something must have changed since then.

Oh well :/

Assuming your rig is more than fine — and this game doesn't require many resources anyway — what's your GPU? Have you tried rolling back to a previous Nvidia driver; maybe quite older, just to verify .... ?

I recalled this topic, where a driver rollback fixed his problem — although different symptoms/another problem.

This is a GTX 660 ( yes i know, kinda old :P ).
But it has no issues with most other games of a similar age to Rain World.

It's just always a bit odd when a game menu is running sluggish, at 100% GPU, with not much going on. Unless it is hiding shader compilation in the background, i could wait a bit and see if it stops, who knows.

Maybe i'll just try playing the game on my fast machine ( that has an RTX ) instead.

So .. menu performance is horrible, ingame performance is OK ( 7% GPU Usage ).

There are other threads on this forum mentioning this too, so it happens for others as well.

At first i thought it was the old "no VSync in the Menus" Problem that has plagued other games, but since forcing VSync doesn't help, it may be something else.

Or it may be a similar issue, where the Menus simply happily swamp the GPU with render commands that are unneeded.

Hah, probably old and gold as well! I still have a GTX 750Ti (2GB) (with ongoing driver support!), together with an old C2Q 8400, and 4GB DDR3 RAM only (Win 10 Pro), and I've recently played Ori & The Will and the Wisps without a problem (I did, however, upgrade to an SSD @ SATA II = still and incredible performance boost + CPU utliz. decrease due to an SSD's IOPS potential), and now Ghost of a Tale!

Anyway, I started playing Rain World with a C2D E8400 (and upgraded for just €5,- ), but never had any trouble, until my HDD deteriorated too much, and started to cause some minor freezes due to (unnecessary) reads/writes after loading ...

Which OS are you on? I assume some basic options via Compatiblity Mode aren't going to help?! Odd indeed ...

Thanks, that helps a lot ! Kind of a strange and obscure way to do it though :o

The non-flat effect doesn't even look that expensive, it just seems to be a few parallaxing planes moving around.

Certainly not something that should send a GPU into 100% mode or lag the menus as it does. Hope they optimize this at some point.

Yeah it drove me nuts for a bit until the flatmode trick was implemented. Im hoping for more fixes and QoL stuff comes with the Downpour DLC too. If not, probably mods.
