Hi,

I’m only using 2 particle Systems without lights Both using 56 particles, and with plane and some meshes e.g rocks, Big rocks with snow matterial. Don’t get how it can be lagging as i’ve got:
GTX 970
i7 4790k 4.00 Ghz

Any advice?

Hey TSDREX,

Other users in this AnswerHub thread are seeing significant lag on GTX-900 series GPUs. Can you explain how you found out that Point Lights were the cause for your problem?

Hi Jonathan,

Some Reason when i place Point of light it lags, But when i turn the Cast Shadows off in the point of light setting it’s lag free. I have no idea why it’s lagging using the Shadows in point of light (i’ve also tried Spotlights with shadows and it’s fine without no lag)
