Thanks for all of the replies and tips.
Apologies for not listing everything I've tried to increase FPS, I just naturally assumed it'd be a TLDR.
Syncing the G-cards, turning off Dynamic Mesh, V-Sync, Reflection Quality, Motion Blur, Reflected Shadows, SSAO, DOF and Sun Shafts. I turn down texture quality and water quality. Set UMA and plant quality to mid, view distance to 10, particles to as low as possible
I try the GFX fixes in game, run it from teh shortcut, I've optimized my graphics card specifically for 7D2d, and I've tried editing some of the storm values.
Lot's of things to try and mix, but still get ugly FPS when I attract too many Z's near those T5's.
I've tried going around teh T5's before starting them and killing anything that moves in a block radius, but all that does is insures that by the time I've looped around, more Z's are spawning where I started.
I'd be fine with ignoring them, but they cause my FPS to drop when there's too many of them below, romping around. They themselves arent the issue, their rendering and tracking are.
Thank you all for the replies, I appreciate everyones input here and I see a couple new things to try out at least.
Hope everyone is safe and healthy, enjoy your week folks.
Thanks, I appreciate it, but game play tips aren't what I was frustrated with. I can do a T5 easily enough, when my Frame rates will oblige.
I've been playing since A-15 and have over 4000 hours played. Killing the darned Z's isnt the issue :-).
It's got to be something with the new city generation for sure. That and the insanely increased spawns, even without Feral Sense.
Hopefully they'll give us more options on control over spawns and respawns in future. If a Z wouldn't respawn for a guaranteed 24 hour window after I kill it, I'd be fine I think, but I have no idea if they'll give us that as an option on respawn rates.
Cheers.
