When Ogryn uses the Big Box of Hurt grenade, the explosion consistently results in significant spikes in CPU Busy time. This appears to impact performance, especially when multiple grenades are used in quick succession or in high-density combat scenarios.
Steps to Reproduce:
Load into a mission with Ogryn equipped with Big Box of Hurt grenades.
Throw one or more grenades into a group of enemies.
Observe CPU usage during and immediately after the explosion(s).
Here is an example with my normal settings:
The top orange graph represents FPS.
The second orange graph shows frame time.
The green/red graph shows CPU Busy and GPU Busy.
Note: The graphs do not have labeled scales, but both the frame time and CPU/GPU Busy graphs range from 0–100 ms. The FPS and frame time graphs update in near real-time, while the CPU/GPU Busy graph updates in 1000 ms chunks.
During the explosion, frame time and CPU Busy spike to 25–50+ ms.
Attempted Solutions (Optional):
I tried reducing all settings to minimal but have the same results:
thx for bringing up this issue. i have a 7800x3d with a 4090 and 6000 mhz ram, i play on a 480 hz 1440p monitor but the effect still is obnoxious. if it stems from the graphics alone it should be simple to offer simplified explosions, i mean it’s pretty ridiculous how it can slow down a new box like yours. but perhaps there’s also latency with checking those explosions with the server.
I’ve had this problem since launch. The only solution is to tweak the ‘particles_capacity_multiplier’ to a value less than 1. However, this will gradually break other particle effects, especially the bomber’s grenade.
Unfortunately, the response I received from the Support Team was: 'It’s been confirmed that we realistically need somebody to be able to replicate the issue on our end.
Regrettably, as this is not a widespread complaint, and due to resource limitations, I’m unable to provide an ETA as to when we will be able to conduct a complete investigation’
