AstroCat Posted August 25, 2005 Share Posted August 25, 2005 Ok, got a new Dell XP gen 2 laptop and a 7800GTX card for my desktop. The laptop uses: NVIDIA® GeForceTM Go 6800 Ultra with PCI ExpressTM x16 ...for the video card. Laptop drivers tried are: 77.24 and 78.11 (current) 77.77 for the 7800GTX card When I dont use AA I get 100 FPS When I use 2x AA it drops to 20 FPS !!!! Something is seriously wrong. Any ideas? I should note I lose hardly any performance with up to 16x aniso filtering. It's only something to do with CMBB and AA that is not working correctly. This is on both the laptop 6800 and the desktop 7800GTX. More info: Whenever any "non-3d" items are on the screen the FPS drops way down. Such as the box around a unit when you select a unit or there is text on the screen. When this is gone the FPS shoots back up again. Or, when you get the info screen for a unit I can go from 80FPS with 8xs AA and 16x aniso to 8 FPS when this screen comes up!! Adding AA and aniso doesn't really hurt my performance at all until I get this 2d bug kick in. This is on both my laptop and desktop computers! Any ideas what is causing this? Thanks!

Redwolf Posted August 28, 2005 Share Posted August 28, 2005 How do you measure these FPS? 0 Quote Link to comment Share on other sites More sharing options...
AstroCat Posted August 28, 2005 Author Share Posted August 28, 2005 Using FRAPS... http://www.fraps.com/ Used very often to benchmark games. 0 Quote Link to comment Share on other sites More sharing options...
Redwolf Posted August 29, 2005 Share Posted August 29, 2005 Are you sure that is accurate? 20 fps should be easy to identify by eye, it should be really jerky. If your screen is behaving normally and scrolls smoothly then I'd say fraps took the wrong number here. Do you have a dual-monitor setup? 0 Quote Link to comment Share on other sites More sharing options...
Schrullenhaft Posted August 29, 2005 Share Posted August 29, 2005 Which version of FRAPS are you using ? It's possible that the method that FRAPS is measuring with may not report very accurately with CM's 2D info displays. As for the 3D selection boxes, I wonder if this issue is somewhat similar to the ATI Radeons and some Z-buffer problems. With the Radeons it affected turn crunching, which seems to be a somewhat different problem here with the GeForce. Have you used any other AA modes ? Quincux (or whatever the 6800/7800 series are offering between 2X and 4X) may probably get better, though possibly similar numbers ? Perhaps there is a supersampling bug in the drivers that is directly related to those particular cards. 0 Quote Link to comment Share on other sites More sharing options...
AstroCat Posted August 30, 2005 Author Share Posted August 30, 2005 I've experimented a lot and I'm sure there is some bug going on with AA and CMBB. It must have something to do with the 2d elements on the screen. When you bring up the unit info screen the FPS can drop in to the single digits from say around 50 to 8 or 9! I can reproduce this problem everytime across multiple computers and graphics cards. I need to keep using "current" drivers so I'm not sure how to proceed. 0 Quote Link to comment Share on other sites More sharing options...
AstroCat Posted September 2, 2005 Author Share Posted September 2, 2005 Ok tried new 78.03. Same prob when using AA. Open info box on a unit get gigantic fps drop, still playable if you dont do anything when you open the info box. It's some kind of conflict with 2d objects and AA. So strange... 0 Quote Link to comment Share on other sites More sharing options...
Redwolf Posted September 3, 2005 Share Posted September 3, 2005 I don't think that Charles had in mind that somebody might need high framerates while a dialog box is open. Do you move over terrain that much while looking at unit data? 0 Quote Link to comment Share on other sites More sharing options...
AstroCat Posted September 3, 2005 Author Share Posted September 3, 2005 No, not really but until recent drivers 2d objects did not cause a FPS drop when using AA. So something now is different and seems bugged. If my computer wasn't very fast like it is, even having lots of targer/movement lines on the screen would now bog it down. 0 Quote Link to comment Share on other sites More sharing options...
Redwolf Posted September 3, 2005 Share Posted September 3, 2005 Well, the latest NVidia drivers certainly don't have the quality advantage over ATI anymore than once made me a NVidia fanboy. Just be happy the friggin' game runs at all 0 Quote Link to comment Share on other sites More sharing options...
AstroCat Posted October 9, 2005 Author Share Posted October 9, 2005 Just a quick follow up. Was totally a driver problem. Using the latest 81.84 drivers and the problem is reduced dramatically. It's totally ok now. ... good thing too, given the recent CM news... /sigh 0 Quote Link to comment Share on other sites More sharing options...
Jamm0r Posted October 19, 2005 Share Posted October 19, 2005 81.84 do indeed fix the bad FPS problem. Unfortunately, though, 8xSAA is now broken in CM with the new 81.85 official betas... parts of the UI are missing and the screen flickers big time. 0 Quote Link to comment Share on other sites More sharing options...
