I have not found that to be the case. TWS seems a lot more resource heavy during boot-up than TOS. Your hardware specs are more than enough. There is not that much difference between a i7-9700 vs i7-4700 for single-thread performance: https://www.cpubenchmark.net/compare/Intel-Core-i7-9700K-vs-Intel-Core-i7-4770K/3335vs1919 You have plenty of RAM and I drive 2 full HD monitors easily with integrated graphics on my i5 laptop with both TWS and TOS. Go to your thinkorswim directory and look at thinkorswim.vmoptions -Xmx768m -Xms32m -Djava.util.Arrays.useLegacyMergeSort=true -Dawt.useSystemAAFontSettings=lcd_hrgb -Dsun.net.http.allowRestrictedHeaders=true -classpath/p launcher-second.jar -Djxbrowser.logging.level=INFO -XX:MaxPermSize=256m Above are the settings that I use. Can use much more than 768m if you want, but I have not found it to make a difference.
