[DEV] Trees rendering overloads the GPU after 0.75.108432 patch
New, WishlistPublic

Description

After 08432 patch I observe high (99 - 100% constantly) loading of my GPU, during rendering of trees, and FPS drops. It leads to overheating sometimes (up to 85 C, while 75 C is normal). It was about 65-75% before the patch with the same graphical settings. I tried to change the objects and textures settings to standart and low, without any effect.

GPU: GeForce GTX 470 1250mb with standart cooling system
Driver ver.: 326.19 and 326.41, tested with both.
Game settings and examples of GPU loading are provided below, maximal framerate is fixed at 45 FPS.
Temperature could reach 84 - 85 C is a long run

So game developers are responsible for your bad cooled GPU ? :D

edit: If your card is overheating problem is somewhere else, clean fan or but better cooling for it..

I have 2 GTS450 and 6 core AMD and trust me its doing some "heat" but i have good cooling for it, so temperatures are at 65°c max

my GTX690 has a hefty fan, i couldnt afford the liquid cooling one like my CPU but o well my rig is special lol

if your cooler cant cool your GPU used on max, you need to change it. Game cant do anything with that...

if you read the whole text, you could see that the problem is high GPU load, that cannot be reduced by the video settings.

tested today on my friend's PC with GTX670. On his standart settings - 60% load on the plains, 100% - in the forest, disabling AA and lowering the settings to "low" values allows to decrease GPU load to 85%, but not more.

Looks like everyone here want 2D trees or what...

I've found the cause of the problem: when shadows are at low settings, rendering of not the trees, but their shadows causing the overloading. I changed the shadows settings to normal, and the loading decreased to 78 - 80%, FPS drops are gone.
Probably iy's really a bug, since lower video settings cause higher load somehow
