| Summary | 0004693: jK's 100% CPU thing is evil | ||||
| Description | I chatted with jK few hours ago, and he wasn't joking when he said Spring must use 100% for better performance. This is a misconception, in Windows it was suboptimal performance instead. He claim overall performance increase (which wasn't detected by any ZKL dev or any players) probably due to unknown interaction of his system. I propose Spring dev to convince jK to remove any artificial CPU waster. jK's CPU waster is bad because: 1) Spring yield no overall performance improvement at all in Windows when benchmarked using Licho's ZK benchmark tool 2) Spring broke thermal management/power management in Windows 3) Spring lag Windows and other applications It result in: 1) laggy game experience 2) overheat & accelerated hardware wear/exhaustion 3) break multi-tasking | ||||
| Steps To Reproduce | In windows, just starting an empty game cause 100% cpu load. | ||||
| Additional Information | implication to hardware (overheat & accelerated hardware aging), no longer just a software bug | ||||

if your point is valid, why do a lot of games don't enable vsync for better performance? also you are way to personally here without giving arguments. |
|
|
also: which engine version are you using? which settings are used? |
|
|
also you should maybe read a bit about busy wait, i.e. http://stackoverflow.com/questions/1107593/what-are-trade-offs-for-busy-wait-vs-sleep |
