New lag

[ash5896]

Hello. I am currently around wizard level 4.5k. Up until now game has run very smoothly with few issues.
I have recently respecce my skills after reading the endgame guide, but suddenly have horrendous lag even on early levels with low level gems (done just to test lag) once monsters are on screen I am struggling to get above 5-10 fps.
This is on a relatively new I5 laptop with 8gb of Ram. Hadnt changed any settings prior to the lag appearing and have tried both full screen and windowed modes with no improvement.
All graphic settings are at minimal and weather is turned off. Have even tried disabling info boxes as this helped in a previous gemcraft game.
Any suggestions of anything else to try as the game is simply unplayable for me at present?


Thanks in advance

A couple things that could help.
1) There are a couple other settings not covered by minimum toward the bottom that help allot.
2) Turn off weather effects (dont use the ingame bonus/cheat thing changing weather either)
3) Dont rush too much I think 2k enemies is about the most you want on the screen at any given time.
4) Rely more heavily on traps. Regular towers & laterns are gpu intensive. You need a couple.. to take care of shadows.

Thanks for the suggestions. Turned out something (I'm guessing a windows update) had bugged my laptop. Had also lost sound from all applications. Only a month old so took it back to shop, they did a factory reset and it now runs perfectly again.

Disable HiDPI might be a answer. Bigger than 1080p causes huge FPS drop.

I found the advice in this post (below) really, really helpful. I went from 10 fps to 30 fps by following the OP's advice around setting default window size and maximising with alt-enter:

It would be nice if devs could take a look as it looks like there are some huge performance gains left on the table.
