Been modding for many years and am pulling my hair out on this one (not much to pull anymore)
Always use Essarrbee's wonderful guide for pointers and a few mods of my own. The last 2 builds, game runs smooth as silk 98% of time...except on load after FT. Then panning mouse causes bad fps lag (almost like screenshots) for a few seconds until smooth. Things different on last 2 builds:
1. modded game on my ssd instead of hdd like before (never had this on hdd...odd) also clean install creators build win 10 (eh?)
2. cannot use breplaceheap in NVSR due to out of memory errors... =0, no errors (oddly enough COULD use it on hdd) exact same system (i7, gtx1070, 16GB system ram) am using nvse_config
3. tried many ini tweaks
4. went back one mod at a time and found NMC to be main culprit..optimized it with ddsopt (again..never had to on hdd)...still there. Tried smallest pack and better...but always used medium before (unoptimized) with excellent results
I know not a lot to go on, but if anyone else has experienced anything remotely like this with a working fix or something close to one , please advise!
Thanks for all you do gang!
