DEV-37067
|
In VWR-12540, updating some OpenGL headers (specifically, glext.h, glxext.h, wglext.h) was one of a series of changes that resulted in an overall performance gain from 1.22. The developer also generated and updated glh_genext.h with extgen parser to ensure detection of gl extensions, from reference 1 from original reference 2 from original
There needs to be some investigation on whether/which of these changes are a win (for 1.23).

btw ive done testing at a abandoned place and testet with fixed env sky etc ... just standing still at the same spot and looking around fast. With the old one ive a dia show slower than 1fps .. with new one much more than 15 .. which is "okay" at this spot (was training island) normaly it should be over 60fps i think .. but i dont know much details about this grafic engine
with this comment ill start with answering questions that allready has been discussed in the main thread and pointed out by Boy Lane and me ... first of all i dont know why im asking those questions, cause it would be easy for ya to build up a test system with normal specs and an ATI Card higher than or equal to an HD 3870 ...
Whatever ill answer now those questions so that someone of the programmers or "discussion leaders" can decide wheater or not this will be applied in further versions of the SL Viewer ... Note: It has been more than once testet that this fix IS working and WILL improve the viewer about more than 38 % on some systems (e.g. my pc) overall performance increased about 50% and more from 2.6 fps to about 19 fps at the same spot (relogging was done fast so nothing else changed much e.g. the crowd dissappeard

To Answer the Issue, if not allready done.. updating the glh libs WAS needed cause some extensions where not initialised / activated that will be asked for activation during client boot up e.g. WGL_ARB extension. The error log was "NO Arb extension present".
Furthermore i dont know why a dev or fellower of this thread said "we dont use this extension ingame ..." why would it be testet if this extension exists IF its not used ....
