I think i found a Bug!

derral

hi there!

just want to give feedback to help the devops. following scenario+problem:

- AMD Phenom II X6 1100T @3,3Ghz | Windows7x64pro | Repetier-host v2.2.4, configured to connect via tcp/ip, but the repetier-server was offline yet

- 8 repetier-host windows opened with different stl files (hey, it's a good viewer too)

- tab-switched to CS:Go game

- and now: as long as i pressed the right shift-key, CS:GO-graphics where jerking - task-manager says: 100% CPU-LOAD, while i press shift... the repetierhost.exe files seamed to be the reason

- now, after some minutes, that i needed to create this account, i realize that this doesn't happen any more.... hope that this info maybe can help you....

Repetier

Not sure what CS:Go graphics is, think a translation error. Maybe g-code. Anyhow I have nearly no load doing this.
Regarding the old processor and OS, what does host report in log for OpenGL. Something lik ethis would be good:

09:59:41.695 : Using fast VBOs for rendering is possible

Most important is "Using fast VBOs for rendering is possible" - that is the fast, graphic card powered 3d solution. With older OpenGL versions viewing g-code is quite slow due to missing hardware support and can easily consume 100% cpu time then.
