i'm testing it now, this new build uses different intensity and grid size vs TT-Miner-2.1.19, now default intensity is only 16 but grid size increased in quite big amount, older build had around 4000 now it has 10000-11000 according gpu you're using 1080 less 1080Ti more, i haven't changed cpu intensity, hashrate is higher than before :

do you think increasing default grid size is good idea and it will help to maintain higher hashrates in longer periods?, i had 14.3mh/sec in TT-Miner-2.1.19 now i have 14.8mh/sec of course if it can keep such hashrates in 24 hour period without dropping shares, i will keep testing it and report results and pool average daily hashrates as well, in TT-Miner-2.1.19 i had around 16mh/sec daily hashrate in mintpond, let's see if new build will be better, by the way newer build responsivness is much slower than older build using default settings, well miner need more time to submit shares, but overall it's pool side average hashrate that matters and if new build will be more effective than older build than new modifications was necessary, let's see how it works in longer periods in terms of stability using different intensity and grid sizes than older build
