VFX Particle strip causes crash
Hi! the version of Unity is 2019.3.12f1
The problem is that I made a game with lots of particle systems that use the new VFX graph and these particles can't render on specific graphic cards.
The exact issue comes from this block :
If I remove the output particleStrip Quad, the game runs fine, but the particle strips are not rendered as expected.
However, if the block is here, the game runs smoothly on my NVIDIA GeForce GTX 1050 Ti but it crashes instantly on my default graphic card : Intel(R) HD Graphics 630
Do you guys happen to know the reason why the game crashes on low graphic cards when rendering particle strips ? Thx in advance
alright imma report a bug to unity because i really don't understand why it's happening
The HD630 is not really a graphics card, it's Intel's inbuilt CPU graphics.
Anything you're trying to do with a GPU-driven particle system intended for high-end VFX, is not going to work well on a CPU. I'd think - though stand to be corrected - the root of this specific problem will be an extremely complicated low-level shader/hardware issue which is not easy to fix, and not something Unity probably care about fixing as the VFX system isn't designed for systems without a GPU.
If you're testing that because you want to see a 'low-end' potential end user spec, I would either seriously consider changing the low end spec to an entry-level GPU, or using the legacy particle system. If you absolutely must have scalability from top-end GPU particles on a GTX/RTX through to no GPU at all (HD630), then I'd think it's likely you'll need to re-create all the effects in the legacy system for the 'low' setting.
