LOD_RADIUS=3.500000 ?

You need to download the Shader 3.0 mod, also, tell me specifically what is what you are not having success with?

What is that and where download it? Well, I realize that the BP=0 and Fiber=0 tweaks doesn't give me more performance with my ATI HD 5870. In former times, with the GTX-295 BP=0 pushed me up with the FPS, it was amazing. Unfortunately your highmemfix=1 was not known yet at these times :) I have tried also a lot with my HD 5870 but I cannot get better performance by ANY tweak. Is that because ATi cards cannot gain performance by these tweaks?Which settings do you suggest to me for my system (check my signature) ?

Is that because ATi cards cannot gain performance by these tweaks?

No, it is because ATI's 5870 and GTX 480 are so incredibly fast, that even using a BufferPool won't impact your performance.Also, not 'ALL' vertex data goes to the bufferpools, only the one BELOW 1MB, anything above 1MB goes DIRECTLY to the D3D API command buffer, you control this 1MB value using another hidden setting in the [bufferPools] section called: RejectThreshold which when NOT present, defaults to 1MB but you can 'tweak it' the lower the value, the closer you get to BP=0 like performance without the instability. Good values to try are 100000 and 250000In your particular case, even a FRESH fsx.cfg file, will give yoiu solid performance, so there is not much to tweak. The only you need is HIGHMEMFIX and the vsync FIX. The shader MOD will also improve your performance but ONLY when flying under heavy weather.

No, it is because ATI's 5870 and GTX 480 are so incredibly fast, that even using a BufferPool won't impact your performance.Also, not 'ALL' vertex data goes to the bufferpools, only the one BELOW 1MB, anything above 1MB goes DIRECTLY to the D3D API command buffer, you control this 1MB value using another hidden setting in the [bufferPools] section called: RejectThreshold which when NOT present, defaults to 1MB but you can 'tweak it' the lower the value, the closer you get to BP=0 like performance without the instability. Good values to try are 100000 and 250000In your particular case, even a FRESH fsx.cfg file, will give yoiu solid performance, so there is not much to tweak. The only you need is HIGHMEMFIX and the vsync FIX. The shader MOD will also improve your performance but ONLY when flying under heavy weather.

@Bojote:would you please be so kind and tell me which settings you suggest for following?First, I start with a clean FSX.CFG, then set-up my realism settings and stuff like this, choose DX9, as resolution I use 6060x1200 (!), I prefer DX9 and NO BLOOM. I'd like to have my scenery sliders full right except Water at mid 2.x. Please note, that I use REX v2.0. My questions:1.) Should I use in REX v2.0 1024, 2048 or 4096 texture in the configuration manager of REX?2.) Should I always config Texture_Max_Load=1024 in my FSX.CFG?3.) Should I use Fiber-Frame=0 tweak, BP=0 tweak, Affinity-Mask=253 ?I don't know which settings and values to choose? there are so many variables. I red also your FSX.CFG but I'm not sure to implement it one-by-one as you wrote, because it was intended for nVidia-users.So what do u think? Are there any other 5870 users which can give me some tips?

@Pegasus1: I have an i5-750 @ 4 GHz and also a Sapphire HD-5870 Vapor-X. Hence we may exchange our findings.I am very interested to get a reply to your questions 1) and 2) as well.Fiber-Frame=0 tweak is not working here.BP=0 tweak is working fine.Affinity-Mask=14 is working fine.

GTX 480s have been very hard to come across but just noticed a local store nearby finally received a couple of them and I'm very tempted to buy one but I'm wondering how much of an improvement I would see going from the GTX 285 I have today...wondering if such an upgrade would be worth the money with these recent FSX.CFG tweaks...?The rest of my hardware is a Core i7-920 @ 3.8 GHz, 6 GB RAM, both Windows 7 x64 and FSX running on their own SSD disks.TIA for any input, comments and suggestions!

It will simply allow for a more fluid, consistent, smooth experience.. and you'll be able to increase AG.EDIT: By the way, starting tomorrow afternoon, I'll be away for 3 days.. no computer access, I'll be attending my brother graduation at Embry riddle ;)He's been dreaming to become a pilot since he was 5 years old :) and on Saturday, the dream is fulfilled... here's a video we created as tribute for him.. his name is Jose Altuve :) and I'm proud!

I have an i5-750 @ 4 GHz and also a Sapphire HD-5870 Vapor-X. Yesterday I ceased using the external FPS limiter and set the internal limiter "unlimited". The VSYNC fix is active. I added the Shader 3.0 fix. Now everything is excellent.With the Shader 3.0 fix I have much higher FPS in heavy clouds and I can set LOD_RADIUS=10.000000. Hence there are crisp textures also in a distance of 16 miles. I am exited.1) I use 2048 texture in REX v2.0. I will even test 4096.2) I use Texture_Max_Load=2048 in my FSX.CFG. I will even test 4096.3) Fiber-Frame=0 tweak is not working. BP=0 tweak, Affinity-Mask=14 and Shader 3.0 fix are working nicely.

OK, thanks for the input! I think I will ask the same question over in the hardware forum as well to hopefully have some more input from those who has already went for a similar upgrade since it's lots of money wasted if you end up disappointed.What a great story there about your brother, congrats to both him for achieving his goal and for you making such a great video!!

All these twaeks are working like a charm but I'm getting spikes around big cities and addon sceneries. Outside of that no problems what so ever.I've got the autogen slider on normal.How can I get rid of those spikes?

lock the framerate or get rid of the bufferpools=0 tweak

*******,Congrats for Jose! That's terrific news! I wish him a beautiful "journey" :( Great video and a fantastic lesson to every young boy or girl that have dreams.

How can I get rid of those spikes?

What's your water setting (Low, Mid, High, 1x, 2x)? Just curious.
